I play atrollie shammy and its the near bast race to play as a shammy, the regen is a big big help when you use canabalise alot (and you do) Lizzy shammys are great because they have the best regen (think about how much you pay in the bazaar for a +1 health regen
) With the way Xp rolls now days, i dont think its all that big a deal, i play a lizzy monk and i went from low 30's to almost 50 now in just a few weeks of passive play.
As Snowiie S said with buffs just from yoru self you will abotu max every stat ans with the addition of POK buffs you can max WIS easy. Shoot, once you hit POP the gear you can get from there alone can about max yoru stats. Just pop into the bazaar, blow 2k and you will have killer stater gear for yrou shammy that will last well into his 40's
What it comes down to is if you just want a toom that you can lvl fast, then pick a class that a human can play
