You aren't the only OCE player, it's just there aren't many of us full stop, else we'd have more game modes.

On the topic of power creep and meta champs, it honestly doesn't matter at all aside from competitive play. At lower skill levels (solo queue) anything works because everyone sucks, and at higher skill levels everything still works because people actually play them well. The meta is really just the stuff that's the most consistent at the specific roles required in a team composition. As long as you have a good idea of why you're picking an oddball champ, and when you can pick it, you're fine.
For instance my current pet off-meta pick is top lane Ahri, since her range, consistent poke damage and slipperiness trashes a lot of the less mobile melee champs that usually sit up there, it works well with how I play the lane and map (I like turning advantages/stalemates into ganks on mid and pressure in their jungle, and she roams really well), and can go into a few roles later depending on how I build. But when I pick her I have to be sure it's against something that can't close the distance well (so say a Shyvana would be ideal to pick into), and that the rest of the team has enough tankiness to allow me to go full squishy up top.
