Its Bronze 5 so it doesn't mean much, but I totally just carried a trash team that had Annie top, Lux Mid, and Braum/Cait bot with some pretty damn amazing WW play.
I decided to try that MadStone build someone mentioned awhile back, and I think that allowed me to stay in the jungle and keep farming after the game sort of fell apart. Then I just started jumping out of the jungle every time my team was getting pooped on and picking up triple kills.
I ended the game with Feral Flare, BotRK, Wit's End, Furor Ninja Tabi, Frozen Mallet, and Frozen Heart and probably had like 3k gold in the bank. I soloed Baron.
Score for my team:
Me 18/3/10
Lux 7/7/10
Cait 6/10/14
Annie 3/10/18
Braum 4/7/22
The other team was both mad and impressed. Its always fun when someone calls you OP.
