Well, some of us still have nightmares from 2016.
(note: Leper Gnome, Abusive Sergeant, Knife Juggler, Ironbeak Owl and Arcane Golem were all nerfed)
Not every aggro deck is brainless, but it didn't take much of an algorithm to run that deck. And it was a terror to play against. I remember holding a Sludge Belcher in my mulligan to try and survive only to be dead on turn 4.
So, it was a very frustrating time. Not much different than when Patches was leading warrior to a bunch of easy wins.
Aggro cards have been toned down over time though. Now they usually feel more midrange/tokenesque. Used to be you'd try to run aggo out of steam as they didn't have draw. Now they have seemingly endless refill. But the decks ARE slower and less brainless. But, I think the whole face hunter era really put a reputation on aggro that just won't die.
why you go hurting my feelings of the days of old when these felt good, when buzzard in hunter is actually card advantage lol
But you are right though I feel the pushed aggro into more zoostyle way of playing is making efficient trades, go face, hold and plan out your attack vs. slap face till its dead.
