Add the ability to view other people's "avatar stats" through the in-room list (Example shown in attached picture). This would simply be your game client viewing other people's avatars and giving you their "stats".
Since right now a single bad avatar can impact performance severely, I believe exposing an avatars "stats" to everyone will help create a social pressure to make it a point of pride to have a well optimized avatar.
Users with bad avatars will be called out and be given notice by other users that they will need to optimize their avatars.
The avatar stats can be colour coded with green/yellow/red to let inexperienced users know that for example 37 materials and 9 skinned mesh renderers is very bad. Currently there is nothing to let them know how detremetal their avatars can be to other people.
