I mean, I could probably be able to deal with it for a short amount of time.
Thing is, it would take away from me doing anything else, you know how many people would jump on that train?
It would eventually just end up being too much. I can imagine going back and forth with someone, they keep saying they want this or that changed, or they completely changed their mind.
Plus most of the requests wouldn't be possible for me to even do in the first place, knowing how some people are lol
Guild fashion has been considered on multiple occasions, it just never happened.
The only things that would probably work, would be contests or event rewards, not so much a donation option.
Donation shirts for guilds would be a better option too, since there's an actual set template and shirts aren't hard.
But that isn't necessarily up to me for it to be set as an option.
