I can understand what you are saying but, that will be alot of custom content designed around an unfinished game. I can see a world were us the players create a bunch of custom content while its still unfinished, and the devs then feeling like they have to limit themselves in some way when they come to improving character customization, they might build it around what the community has uploaded which I think is bad (if that happens). Atleast get character design and customization 100% complete before allowing custom content for that in particular, I don't honestly think it is complete yet at all..? If it is.. then alright.
!!!Warning!!! a personal opinion: I also find the workshop annoying because of constant downloads because I'm the minority with absolute trash internet, but I still find it somewhat annoying regardless.
Its probably going to come anyways just voicing my concerns
