ZZ'Rot portal exploit?
So, using five ZZ'rot portals to block the middle lane of minions and, once they expire, releasing an almost unstoppable wave of a ridiculous amount of minions. Exploit or not? Just played against a presumably premade 5's team that did this on Black Market Brawlers with entire waves of Razorfins. Instantaneous death if you aggro them. Sure the game mode's almost over, but even in regular play it's fucking stupid. Riot, please, fix this.
