With how busted supports are, I'm genuinely thinking of switching to them as my main.
There's literally not enough bans to go around with all the OP champs right now in league... but if I had to pick my top 4 I don't want to play against, those champs are Janna, Lulu, Alistar, and Thresh (Kai'Sa is definitely one of the most busted champs in the game as an honorable mention, but these supports are aids). Holy fuck these champs are the epitome of cancer.. Ali and Thresh are unkillable even with no items, Lulu polymorphs you for 3 seconds every 4 seconds so you might as well just fucking afk... Janna stops you from doing any damage whatsoever not only to champions, but also to turrets. If that wasn't enough, now every role is taking fucking bone plating when they see any kind of assassin in the game making their combos do about 1/5th of what they should early game. This game is a joke, might as well just play supports or tanks with bone plating and if your enemy doesn't take it, it's an auto lane win.
