This is a question that I've always wondered. I've been wanting to make a 20 team of 10 druids, 5 shamans, and 5 dks, but I'm not sure if having more of one class is better, or having more classes. i.e, 5 druids and 5 hunters instead of 10 druids. I realize more of one class is simpler, but I want to know what is the most powerful.
