Hello Magwo

Good to see another warlocks+priest multiboxer

I would say go holy with your priest, and lifetap/aoe heals give you virtually infinite mana, and when you get CoH thing really will speed up. You should also check out the threads wich explains how you can use mousetargeted aoe spells within macros using a map-ping. This can be quite useful for some aoe-grinding. Personally I think you should do most questing, and not much instances to level fast. You get a lot of xp from quests nowadays, but as you allready have mentioned, avoid the collect quests (allthough it can be wise to check what followups you get, it might be worth it if there is a series of simple quests afterwards)

I just have a question for you. Do you plan to mainly pvp when you hit 70? If so I will strongly advise you to reroll undeads while you still are on the lower levels. Trust me when I say that you will have a huge problem with aoe fears without (yes, I know you can get trinket,but you will need both that and will of the forsaken)
