I agree that items are very strong in these games, and something should be done to add some sort of balance. Adding a cooldown to bow and wind charges (and dorys pls) would certainly help make the game better. Alternatively, they could reduce the amount of each of the op items people can buy (arrows, dorys, wind charges) in some way (reducing emerald gen speed/removing the em gen speedup, reduce the amount of these items each shop can carry (eg. 2 dorys per shop), or up the cost of these items (make dia armor cost more emeralds pls))
I agree that there’s a problem with overuse of these items, and this post certainly proposes a solution.
