When you destroy an inhibitor, your minion does a "king me" and flies back to base.
Carrying the magical crystal that will hulkify the pants off of his peers and make super minions. If you don't have a minion there, one runs at forest gump speed from your lane, glowing gold and immune to chuck norris to claim the crystal.
Reason:
So new players can make an instant association between inhibitors and super minions and won't have to ask experienced players
"Hey we were pushing and all of a sudden our minions got big and nasty, did that have anything to do with the stuff be blew up in their base?"
Logic and stuff.
Besides it'd be cool if the glowing gold minion on returning the crystal became "disciple of Jesse Perring" and became a super duper minion with like, flames and torpedoes and shit.
