I've been 2boxing a warlock and shadowpriest, and they are both 44 at the moment, and have been kicking total ass at leveling. The Voidwalker tank has proven most capable. However at 48 they will have caught up to my hunter, and I'll be expanding to 3boxing. Which leads to the question: what should I have tank?
I can see strong benefits with either the voidwalker or a bear/boar/something else as a tank, and benefits from the pet that isn't tanking (imp for life, hunterpet for dps). Granted stuff wont live that long with 3 heavy hitting dps unloading on it, and so what really would swing me to one side or the other is which pet can tank multiple mobs the best. Voidwalker has an aoe agro ability, on a pretty short cooldown, but if a hunter pet tanks I can have the imp put fireshield on it.
The long term plan for these guys is that at 70 they will meet up with my druid and mage, and I'll be attempting 5man instances with Bear tank, priest healer, and the other 3 as dps. (Yes, 5 different classes is asking for trouble, but I didn't go into multiboxing because it's easy.) None of that really matters yet, as I've still got a number of levels to chew through.
