I see your point, I have two locks at 58, will try and get 2 more.

I tried out an experiment yesterday, I was feeling good after my four hunters hit 61, so I decided to go to Ramps with them without a healer.
I downed the first boss (Gargolmar) on my first try, and lost one pet, all hunters are BM.

I am kind of shocked still, I know this will not fly in Heroics, however I was pleasantly surprised at how well mend pet is healing at this point.

I plan on adding my 65 priest to the group at some point, however this was fun to say the least!
