Actually, ya. When the expansion was first talked about, I reinstalled it and played it for a bit to check out a bunch of the free stuff they put into the game. Devastator had a very specific path it went down at release and now you can basically pick w/e on the talent tree. Then, outside of classes/talent trees - a bunch of mods have been changed and added. Though Ive heard that if your armor was already god tier, there was only slight changes that you would make to get back to God tier after the nerfs etc.
The thing that gets me is that Ive barely seen anything presented about the expansion. I feel like a normie wouldnt know about this expansion coming out at all.
