So we know PvP ranks will not be a thing in Phase 1. And 90% of people at the start would be focusing on grinding to level 60.
Only scenarios that come to my mind when being engaged in PvP combat. Would be either you take someone's mob and they get frustrated. Or you're in someones grinding spot.
Any takes how you can be there, with minimum PvP Engagement during leveling at the start? Guess try for 1-2 hours to see if you indeed get picked on 24/7.
Alternative location (Horde & Alliance = Arathi Highlands & Desolace), I'm more familiar with the Horde faction. But pretty sure there is an alliance quest hub at the northern part of Desolace.
