6+ months into Legion, and I am still playing 5 or 6 nights every week.
I can't say the same for WoD, by six months in, I think I was already unsubbed, and if not, just playing couple nights a week. I think Legion has been really good to date, especially for a game that is 13 years old already.
Could Legion be better, yes of course, but could also be a hell of a lot worse too.
