Classic wow 5man for new boxer

[MiRai]

Going to play classic wow. New boxer, I want to start off with a 5 man team of all the same class. Is this even possible in classic to get bosses down with all the same class?

Yes.

I'm thinking of Druids. That way I can try having a tank and healer when ready.

I don't know the answer to this, but I don't see why not. However, there has been endless discussion of classes in the WoW Classic sub-forum.
