To speak directly,
imho casual players act as cattle in PVP server for 24-7'ers to camp on for honor points. PVE server is definetly way to go if you can not commit huge amounts of time to the game. PVP is 80% gear 15% skill 5% class in massive party-vs-party enviroment. And raid aquired gear is so much superioirty, you will end frustrated without it.
Ofcourse tough its fun for the first 2 months, when everyone is equal what it comes to gear, but then it gets nasty. If someone dosn't belive me, duel me sometime in Arathor to see the difference. (and I'm 100% PVE talented warrior)
Just my 2cp about PVP servers.
