4box pally, mage x2, priest

Hi again.
Back from quitting after wotlk. So I made a new team yesterday as I realized playing just one toon wasn't for me ������
Pally tank, 2x mage DPS and priest heal. Have one open slot for my wife to jump in and join for instances.
I have one question tho, will I have trubble in instances when I'm alone? Since I'm lacking one dps?

Playing on EU Pyrewood Village alliance btw

i would 5 box and just rotate one out for your wife ..you can always go do random quests on the toon(s) that fall behind when your wife replaces them.
