It is an experiment, it might get reverted again, but it will be interesting to see how it turns out.
The idea is that archery should not get nerfed by decreasing damage or increasing randomness, but should take more skill to handle. Bows should no longer be lasersighted sniper rifles, but you will have to lead your targets and take the trajectory more into account.
If it will not get reverted, bows might get more accuracy or more damage to compensate, we'll wait and see how it turns out.
(Oh and this was my idea)
I don't mind the trajectory nerf, I can still shoot speeding horses from across the map without missing. It's throwing me off a little for longer range hits, I got to get used to it. There needs to be some tradeoff though, yeah. I'd say add in more accuracy and less randomness, buff accuracy.
