There’s nearly no reason to play on a PVP server. You’ll get ganked leveling up with no chance to fight back. Once you get to 60 you’ll either be too weak to fight the people who are geared-up or they’ll fight you with multiple people on one.
The amount of good, fun, challenging PVP fights that you get will be nearly none. If you want to open world PVP you’re basically forced to become a ganker. Or just never PVP…in which case you should be on a PVE realm.
Unless you plan on killing people who have little chance to fight back you’re better off rolling on a PVE server, leveling and gearing more quickly, then PVPing in BG until you’re sick of it.
