For one I am not a "kid", that would be a baby goat. And the reason I suggest premades, is they are usually better geared players and alot more organized. As for a five boxer not making much of a difference.. I took my undergeared druids vs mbxa outside of Orgrimmar and almost single-handedly took him down, just ask him. If I would have had someone to assist with an aoe stun it would have been all over. In this example all it would take is five to six people. With decent aoe damage and at least one of them with a way to lock him up for a moment. Heck I was in boomy spec and I am geared for resto, so if I would have had some spell pen I am sure I could have done it myself.
The issue, in my opinion, is not people unable to take down a boxer. It is a clear lack of skill and/or coordination.
