Server alert:
I paid big money a year ago (after a several-years-long absence) to transfer my warlock main to Earthen Ring RP-PVE. The server was phenomenal-- super nice people, an older crowd, nary a trace of the ignorant, illiterate "WoW kiddies" the game is so well known for....and then two months later, Blizzard instated "cross server zoning" and it all went to heck.
Now dweebs, jerks, and illiterate dps meter freaks have overrun the place, because a bunch of servers all share their zones with Earthen Ring's. All the servers are like that, I presume in an attempt to revive some of the quieter areas in a game where everyone's a 90 these days....
It sucks though. If you are going back under the 7-day free reactivation, then fine, check it out. But I wouldn't pay good money for it, because chances are the RP-PVE servers are all cross-server zoned with idiot servers. It totally changed Earthen Ring for the worse literally overnight, I'll tell you that. My whole guild quit at once, including my daughter and I, and I haven't been back since.
