I've never minded having a Pal/SK in the group to tank. It only makes my job easier and the difference (time wise) to make up the supposed exp you lost is minuscule when compared to how much time you probably put into the game anyway.
Plus, when you group with OP, you're pretty much guaranteed to be fighting a train of 2-5 at once, which always helps that exp bar inch forward.
