Well i use both.
I use my 80 pala for farming herbs and mines atm in Northrend. My 65 DK, is Inscripter and runs parrot runs for me in STV.
I Dont like to use my pala for parrot runs, because the mobs are so low lvl, and the pull ability for paladins costs 1.6k mana, so my pala will drink constantly.
