Having people show up as generic models disregarding gear, and hairstyles, yes. That would probably actually fix a lot of it. A good portion of the data send would be reduced.

And it's not like you'd care if unknown miqo'te player #324 standing on the other end of the battlefield wears DL or looks like a generic mage, with a set color of hair instead of pink/green/blue-ish gold. Even less so when you and your party are busy fighting something like Behemoth and Odin.
