PvP Servers: On a PvP Ruleset server, PvP flagging is determined based on the zone your character is in. If you are in a zone that is affiliated with your faction, you’re not flagged…but you may voluntarily flag yourself. If you are in a zone that is affiliated with the opposing faction, you are flagged for PvP. If you’re in a zone that is shared by both factions, you will be flagged for PvP. You’ll have plenty of opportunity to run into your enemy in a shared zone and slay the day away. If you try to go into an opposing faction’s city, you are flagged for PvP (though, this is redundant on a PvP server, because you’re likely in that faction’s zone anyway).
From Da wiki. IF that makes sense. So far I am having fun, I might wanna try and engi or spellslinger next. Warrior is a bit..bland.
