The only thing the "PVP" in a server name means is that you can do world pvp, which these days is only ganking. Arena, battlegrounds and Ashran are all active on Magtheridon, just like any other realm.
So far I enjoy it. Though like Tightpants said, I'm happy I did not pay 109 for it. It isn't worth that much, but for a normal priced mmo (For when it releases I mean) it would still be worth trying out.
