I would wish for something of the following, i can't quite decide:
have riot apologize publicly for releasing garen and then removing him
have balancing acts taken into a vote. buffs/nerfs/remakes/etc.
i think the winner would be a multi-team map. maybe 2v2v2 or 3v3v3
or even other game modes, like CTF amongst others.
c'mon riot, you came from a custom map editor, make come custom games please!
p.s. i wish for the pirate tank i know you're making to be out now, not suck, be full of win and ale, allow me to purchase him early and settle the ninjas vs pirates dispute in ranked 3s once and for all =O
