Yes, PvP is fun xD
But yeah, beware of those people that NotMyWay mentioned ... People that will hate you for "healing yourselves too much" or "buffing up with the protect and resist buffs" and "restoring yourselves" >__O
Clerics are really hard to kill in PvP @-@; I killed a cleric a level below me yesterday, just as he healed. And it was very, VERY close >O<;
