The activity level difference between RP and Normal WM shards - RP shards are too quiet for my taste… or I was usually on overflow shards during my Defias WM days. Either way, Normal WM shards have been more fun in my view.
Community is the only other aspect for me - I want to be on a server that’s at least historically known as good for WPvP, more potential for WPvP guild forming or joining. That seems to be Defias Brotherhood, shame it’s an RP server. Foolish Whisper are on Defias. My current server Outland has a WPvP guild on it, Honor Capped - any other servers with WPvP guilds?
