I was having fun at first but...
I was really enjoying this game mode at first, but then the long queue times hit. It became increasingly frustrating to have to wait over an hour just to get heavily screwed over by bad rng, and someone steamrolling your whole team because they stack their best unit with completely BROKEN items. I'm still playing and learning more strategies as the games go on, but it is frustrating and riot have a lot to fix before making this an official game mode.
