i'm not sure i get what minions dematerializer rune is used for
sometimes i take it, it help me farm cannon minion so i'm not susceptible to poke when i try to last hit him
but when i see pros streamers i often see that they use it in regular minions
they do it to freeze/defreeze wave effectively?
bonus question, to freeze wave you take out casters first or melee? which of them deal the more damage?
