Hi there :) There's no auto potion drinking — I'm still looking for the right balance between auto-play and player control. Some heroes may end up stronger in the future and be easier to play, but the balance is still being actively worked on. For now, I've made the game easier to play so that later on people can compete on clear speed with their own builds and tactics. That's most likely how it'll end up: even with imperfect balance, different players will be able to post better clear times, because if you clear a wave quickly, the timer to the next one resets. =)
