Hi, i found out a verry nice way to powerlevel low lvls thrue the worst lvls in my oppinion of the game (1-30)
I started boosting my brother that was lvling a lock, normaly whit my 80 warlock but the XP wasent rly that good.
So i thought of the oldschool way to get lowlvl full xp from mobs using pet, low lvl tag the npc and pet kill it.
I summoned my VW pulled half of instance and used my pet to AoE Taunt, then he start wacking on mobs until he crit and my brother got buffed whit Demonic Pact.
Then he leaves the group and start casting Rain of Fire, becuse he got around 200 spell dmg from my pet the mobs go down fast and he gets 100% of xp the from mobs.
Important that the warlock dont do annything to the mobs, you can heal the pet but just a hit whit youre wep and the lowbie wont get 100% xp, and the lock only got 1 min before he gets kicked out of the instance.
In Stockades he ding twice each run whit RAF.
Can do this whit anny class that got a decent AoE spell, if the lowbie is struggeling get a druid to buff thorns on the pet, when he then taunts wait until the mobs are around 10-20% leave group and AoE them down.
hope this helps
BTW havent tested it since last patch that changed how mob tagging works
