Be A Minion Mode!
You get to be a minion! Only one summoner per team gets to be the tank minion. The rest are free to choose fighter or mage. Mage autoattack scales through Ability Power, or through a hybrid. Not sure what the QWER would be, but I'm pretty sure the tank minion player would be able to transform into a super minion.
Maybe QWER can be summoner spells? So you can get 6 summoner spells.
