So, I’m a very casual player so I could be wrong but what’s with the ammo system? Why not have the cooldown timer always running and giving you access to another use of a skill up to the cap? Would it break PVP or something? The current system where you don’t get stacks until you’ve used all the charges is really annoying as it feels like sometimes you should blow the last stack or two on purpose in order to refill the rest. It feels really clunky and not fun.
TL;DR make “ammo” skills recharge continuously.
