I'm 3 boxing Mage, Enc, Druid in feerrott the dream but the xp seems kinda low. I've been grinding on the lizards and turning in the repeatable kill quest. All 3 are heroic characters and have some augments now. 1 j5 merc is available for healer or dps. I was thinking old bloodfields but I read on the forums that the XP in that zone is horrible even with it being a hot zone. Anyone know of other places that might be better xp?
First, get your J5 mercs. Next, do all the quests in House of Thule. Once you have a full set of augs, then I'd try experimenting more around HoT, or move to grounds.
