What is your favorite off-meta build/champion?

Well, it is simple. We all know and love/hate meta in the game, but from time to time experimenting is fun. I usually experiment a lot with a lot of off-meta, almost troll builds/champions. What are your favorite?

Maybe my favorite is Quinn mid. She has pretty strong early game, decent disengage. She actually scales decently in game and if she get a kill or two during lane phase her roam with ult is excellent. usually build heavy crit, rushing shiv. While that may not be optimal it is very fun. That makes her clears very fast, so she can spend more time roaming around the maps, killing other players, taking turrets, etc.

Another one I like is duo tank bot-lane, rushing 2 relic shields and aggressive off-tank build on both. While it might be hard early on later in the game it becоmes very fun with all of the engage and damage.

Also almost every ADC can work on top-lane, if you know how to play it. Kinda depends on the enemy top-laner, but still might be fun.

A few weeks ago I would also mention duo-mage bot-lane, however that is pretty much meta now.

So, up to you guys. What are your favorite ways to break the meta?
