The AI must have taken a disliking to their cascade nerf a while back, now they are fighting dirty.
How you ask? they can now do this;
They sucker punch you before the match even starts!. Talk about a low blow
(magic happens at the 00:35)
Well back to all seriousness, I think it was something to do with something to do with the previous match effecting the next match hense why i started the vid at the end of my last match, either that or i was unlucky enough for the match to start with a match up straight away.
Funny bug though, has never occurred after over 500+ hours though.
