So I tried boosting my new pally last night in Deadmines with the hunter, and I'm pretty convinced it's better than druid or rogue. Why? Range. I can right click a mob and it pretty much instantly dies from a shot of my S2 Xbow. XD If it survives, I ignore it. The pet will finish it off.

The biggest problem I had was the alt getting mad aggro and getting instagibbed. I luckily found a lowbie who followed me around for awhile, so I just invited them and said, hey, heal my alt and I'll set it on /follow on you, just hang far back, loot all you like. Pretty convinced this is the best way, cos otherwise, I need to manually make my alts hang back and move them forward every once in awhile for XP.

Overall, the XP/hr. was just terrible. I'd only do this for loot. Otherwise, questing is much faster XP than boosting in the low teens.
