can i do this

Go AP Blitz mid? Sure, just make sure you test it in normals before trying it in ranked. It's not meta for a reason.

Steal your own jungler's buffs constantly? Only if you want to lose the game while being rightfully reported for griefing.

Bully somebody into giving you their lane in Blind Pick? You can get away with it, but you're an asshole if you do, you're harming your team's chances of winning, and you're part of the reason why Blind Pick is such shit.

id have to kill someone
