I see I have been mentioned quite some times here.
So let me put my two cents in:
Take the job of exporting/hardpointing/hitboxing off the modelers shoulders.
You will remove an extra demotivation factor from them and this will allow for one skilled person to supervise and be responsible for game-ready files. It is a tedious work, but it is much less than modelling.
Demand too much and no one will be willing to do stuff. Well, not me, at least, not anymore.
I say take those models that are approved by players and are better than placeholders, give them to a dev and let them export.
If you say it is too much work for devs, then I say it is too much work for modellers, and thereby I excuse myself and be gee-tee-ef-ou.
