They have a Steam forum that I assume they're going to continue using, right...? (I hope).
Even if that's the case, of course, that still cuts out a small minority of people who don't have a Steam account - IE me.
Publically accessible forums without any additional layers of crap to register (like this one!) are getting kind of rare. On top of that, forums always feel like the best way to keep information and solutions to problems organized, so I feel like they should always be the priority to have for software like this.
If we assume they'd stop the Steam one, too, then presumably everyone will either need to fumble around the weird ghost-town style servers of Discord or presumably smack their head off a chatbot in a desperate attempt to get an answer to a question, rip.
This does suck a bit.
