Firstly I'm not downplaying their effort and I understand that they tried to make characters model fit the region. However, the default model are ethnically ambiguous enough to be used instead, aside from hair colors it can be passable as Asian with the right skins and complexions.

My suggestion is revert back to using vanilla character models, but adjusting the hero randomization pools to only give out Asian looking characters, that way we don't spend too much time trying to fix thing that already exist in the game, and players can actually use character presets from vanilla without crashing.
