OK So where to start?

My 4 x Shabooms are in outlands, grinding on the double XP buffet that is Hellfire Penninsula (55.0000 - 56.0000 in 4 hours last night on kills alone@199xp/kill).

I'd prefer to grind instances and save the quests for mount cash.

Any recommendations on where to start? At what lvl is reasonable for the first outlands instance? and which instance?

thx again.

As mentioned in the "1-70 in 24hours lolol" thread, SlavePens is your best bet with a 70 boosting, any should be good by yourself. Slave pens mobs are within 8lvls of the 70s and still high enough to be good exp for the lowbies
