If there is one things that's great about tiering systems is that they're inevitably pointless in the face of hax. Some of you may be too young to remember, but most serious roleplaying forums used to have a few characters like this. We used to call them "bouncers"(for obvious reasons). Essentially, they were peak humans who would invalidate your super-duper special OC when they(or the OP) didn't think it was cool to fuck over a thread for your power fantasy. It's the kind of character, who is barely wall level, but who can shitstomp a superduper-hyper-omni-mega-omni+-hyper-perfect-versal++++++++++ god because their hax ability is literally "within x-squared kilometers, objective reality now applies and supernatural stuff no longer works". So now your hyperdimensional loli is facing off against a super heavyweight MMA fighter with a shotgun, and your powers don't work anymore. Get fucked, kiddo.
