ADCs are optional now.
Last game I went Jinx and had to fight a Brand with Leona support. It's obvious that the crit nerf is too much that ADCs just aren't even worth playing anymore. I ended up feeding like hell, and couldn't farm that well before an opponent took me down. It was at that point that I realized that my main shouldn't be played anymore. An entire class, once relevent, now not worth playing due to Riot changing what isn't broken. I am glad I don't give them money anymore.
