I have exactly the same problem, i’m nearly always in wvwvw when I play GW2 and i’m getting tired of crashing at least once per 30 minutes, sometimes even 3 times in a row within 10 minutes. It started on the borderlands so I played EB but now it happens there as well… Im from Underworld btw.
Edit: It’s happening in the normal world as well now, not only in wvwvwv.
