When I saw the title I immediately remembered the Hexakill game on the LCS All Star, it does have some nice benefits and the ganks were awesome, but I think it would require a lot of practice on the current meta and can only be played when you have 5 people on a team. Would be nice to see it though, maybe comeback with the ADC mid laners and leave the APs on bot, since they can usually handle 2v1 situations better. Too bad my favorite role would disappear.
