I'm boxing a ranged cleric in front.. with a few heals, and a ranger behind so the pet tanks. I didn't want to end up with two of the same class.
They have completely different abilities.. but I just made macros and stuck them on their action bars so they fire off together when pressed - things die fast .

I have done the first two instances ok.. (joining the lfg). Is it possible to take two dps toons into randoms always.. or are some too difficult for that?
