So, what's your plan?
Dusken or Brevane?
Quests or Instant Adventures or PvP?
How many dungeon runs are you planning?
Where will your gear come from, quests, crafting, dungeons or carnage tokens?
Probably Brevane to start. I liked Cape Jule and was a bit turned off by the early mech quest in the other zone.
Quests, occasionally taking a break to IA, and obviously a few onslaughts mixed in there.
I'll likely skip dungeons during the leveling process. Being a cleric, I'd expect to heal, but I'm extremely out of practice and haven't messed with new healing.
Gear will likely come from quest upgrades and I'll save my carnage tokens (forget their name) for the biggest potential upgrade, like a weapon.
