Yeah, really, I think that our first priority needs to be figuring out what the hell overcentralization even is. Honestly, it's the only way we're actually going to get anywhere with any of these bannings/unbannings. Perhaps this should be part of our rankings?
Garchomp would probably be #4 for me if it weren't for the fact that we don't know what the definition of overcentralization is.

I don't even know what kind of argument you're trying to use. You can't figure out what overcentralizing is without it being completely arbitrary at this stage. Considering how long this thread has been around you really have no excuse.
It has been discussed. "Overcentralization" is a moot term that means nothing at this point. It has never meant anything, if you even paid any attention at all. Stop throwing the term around like it means anything.
Secondly you also assume "overcentralized" is the only argument that was around with Garchomp - that isn't really the case anyway.
