I can't agree with that. It's the arrow that impacts the target, not the bow. Strength and coordination should influence the impact of the arrow the same way someone throws a javelin or uses an axe. The bow is just a medium to that extend.
I would understand if the rank of the bow determines the max range of the arrow only, but nothing more than that. Adding minimum/maximum stat requirement to its use makes no sense when any other weapon (including ranged such as javelin, shuriken, kusarigama) do not have these.
The bow itself is what determines the force, speed, and range of an arrow. That's why the invention of the longbow was such a devastating thing for armored units, because it could fire from farther away with more force. The arrows hardness/quality is only really determining if it can survive the force of the impact or is destroyed by a jutsu, etc, and of course if it can pierce the target. In regards to 'nothing else having minimum stat investments' you aren't going to get far without strength enough to lift and swing the weapon, or the coordination to utilize it in time. Not only that, but because of the very powerful ranges involved in a bows use it makes perfect sense to have a minimum stat investment in order to use a bow of a certain rank.
Your D-rank shuriken won't break because you're throwing it with A-rank strength. But your D-rank bow would snap if you pulled back with A-rank strength. An A-rank shuriken thrown at D-rank strength won't do much. But don't even try using an A-rank bow with that strength.
I believe you're confused, a D rank bow won't snap if you use A tier strength.
Allow me to clarify the rule I believe you're misinterpreting.
Maximum Distances are determined by the Grade of the Bow. Keep in mind these are base values that assume the Draw Power of the Bow is equal to its Grade; Bows can have Draw Power of a lower quality than their Grade, but a Bow can never have a higher quality Draw Power than its Grade without breaking. In order to wield a Bow, the user will need to have Strength at least 1 Tier below the Draw
The highlighted line in particular is where I believe you got that assumption from, where all it says is that an A grade bow cannot have a draw power of S without breaking when one attempted to pull it. This is to simulate the tension a bowstring puts upon the material of the bow. The draw power, is the tension, you need a certain amount of strength to overcome that tension in order to pull the bowstring back. However, god forbid if the tension is higher than the bows quality, or it'll snap in your hand.
To the other part, absolutely, don't try to use an A tier bow with D tier strength, a bow that can fire 1.5 kilometers, etc.
What's the farthest possible one can throw a shuriken? Let's find out.
Let's just say a shuriken/kunai is moving at X++ speed
after 20 meters it drops to X then we'll drop it 1 rank per 30 meters
S = 50m
A = 80m
B = 110m
C = 140m
D = 170m
E = 200m
A rank bow shot = 1500m if you didn't know, and it maintains the same speed/power throughout it's travel the shuriken slows down and therefore loses it's potency as it goes.
Of course that kind of range/power ratio is going to come with some sort of stat investment. Like having a strength of at least 1 tier lower
than the draw power (Which is equal to the quality)
So that same A tier bow, only needs B tier strength to draw and fire.
It does however need high coordination to aim such a shot accurately, and perception to track the target.
In regards to 'eagle eye' being free, it is free, because you get it as a perk no other skill/user gets upon getting A tier perception with the Kyujutsu skill.
Retry this with a C-rank perception starting genin and show me where it is 'free' in comparison to a D-rank genin ninjutsu user who gets chakra reduction on their element. Right. You won't have Eagle Eye at all. Why? Because it is not free as you claim. I believe you confuse 'restricted' with 'free of cost'. Yes, it is restricted to kyujutsu specialists. No, it is not free for kyujutsu specialists.
I do not believe that looking at high-tier shinobi as the standard is a fair judgement of the perk. Or anything else for that matter. If the perk is supposed to be a benefit or bonus for picking the spec, it should be available right off the bat to all who pick up the spec. Not just to a select few who shoehorned their build around it.
This is why I vouch for a 'Eagle Eye' ability similar to Sensory's jutsu. It makes it available to all practitioners, not just high-end shinobi.
Show me the genin with C tier perception that can fire bows as far as A tier perception would need and I'll show you someone who has no business making their own stat spread.
To that end however, I believe you confuse 'free' with 'if I don't get it immediately, it isn't really free'.
Does unlocking it require an investment into a stat that fighting in that method would need to level up anyway? Yes absolutely.
Does that mean you get to say it's not free? No, because the term free in this case is stating that should you have Kyujutsu, and obtain A tier perception, you get the 'Eagle Eye' perk for free. So if you meet the other prerequisites, you get that additional perk without having to spend anymore exp.
Your idea? Involves giving a technique similar to the selling point of another skill to Kyujutsu users for free.
Good luck with that idea.
Imagine a target with A-rank perception and B-rank coordination (or vice versa, whichever), using no weapons or armour. What do you get? Someone who will jump 1 meter to the right as they see/hear said arrow come in and you'll miss because you can't manipulate flight trajectory for free. To top it off, they won't have to pay for the weapons or armour. Because if they had that done, their A-rank armour will additionally safe them from a lethal strike. It'd cost no chakra to dodge the arrow either.
Yes, the range is impressive. The power, however, is just as easily negated as you can fire it.
Imagine trying to use what your target COULD do or have as a balancing point.
You can't utilize the potential actions/equipment of another target in an argument, only the theoretical potential of the attack itself. NOT, what could stop it.
What if I'm firing an arrow that cuts through the air without a sound? We're on a magic shinobi roleplay site, and that's a fairly decent idea for an enchant to slap onto an arrow.
What if I'm firing an arrow that reduces the quality/hardness of equipment as it strikes by a tier? Also, that's still A rank force slamming into someone, that's not going to feel fun.
If someone sits there and tries to say they knew the arrow was coming without covering their ass backwards and forwards, they'd get called out for metagaming and their post requiring an edit without a second thought.
Am I saying it's easy to hit someone successfully from that range? No, of course not, I'm saying it's possible to, which is more than anyone else can do without investing at least 30 chakra into the attempt, the equivalent of an S rank jutsu.
Bottom line? Kyujutsu can successfully attack from stupendous ranges with absolutely no cost.
Does Eagle Eye need some clarification? Yes absolutely
Does the entire system need to be reworked? God no, unless one wants to nerf
