I think it shows more that people only play certain characters at tournament enough to be logged as high level. For example, I’m pretty sure deluks is high level with Argagarg. It doesn’t matter though, because he never plays Argagarg in tournament. The ones that are verifiably not at the highest level are the ones that are less tall and fatter but the bubble is not near the top. For example (and I’m not calling him out, it’s just the first one I saw) djister’s Rook. He plays Rook enough in tournament for the model to have a level for him, and it’s not at the top. So not universally having flatties does not mean they are not universally high level, it just means they don’t play everyone all the time.
Another Example: if you were to look at my chart, the only character I’ve played enough in tournament for the model to get a good idea where I stand and that also ISN’T near the top is Jaina (and maybe Lum). At least that is if I’m reading these correctly. @vengefulpickle tell me if I’m wrong here.
