Yea that's the underlying idea behind the teams I put together. They offer simple macros along with being able to use the same macros between teams, like the paladin tanking one. Also with using 3 of the same dps there's less micro management.

I'm actually doing what puppychow has stated and only leveling one group up to 80 because I know once I hit 80 I'll have my hands full. Plus with the toons that I have gifted levels I have almost a second team ready to go if I ever get bored with this one.

But it all depends on what your goals are.
