I find Nexus Blitz to be utterly disappointing for one very simple reason.
It's just another playground for the same Champions that absolutely dominate every single other mode, but a degree worse. We're already losing to these Champions left and right, and we're expected to view a mode where it happens to an even more egregious extent to be fun?
If Jax, Kayn, Brand, Zed, Camille, Yi, Yasuo, and the rest of the unbridled dev-pet crew happen to make it past draft and load into the match, the game is over.
There's too many to ban.
I'm not having fun.
