There’s a pretty healthy community (200+ so far!) trying to foster organic RP on WrA, with an initial focus on Alliance RP. Literally hours before your post we hosted a hugely successful event in Cathedral Square that easily had 50+ people at peak times.
Walkup RP is waning, but we are also working to bring that back. If you’re serious about making friends on WrA Alliance (or neutral/Horde of course), come join us over at the Wyrmrest Community Project!
