Welcome to the world of boxing.

I run with 2x5 teams. One has no duplicates (all classes are different) and the other runs tank + hunter (offtank on autopilot) + 2 shammy DPS + druid heals (l like hots ticking - needs less concentration on heals) - working towards my first 10 man when both teams hit 70.

I don't think I get optimum performance, but I can constantly play with stuff and fine tune things because of the sheer number of options - e.g. currently thinking about moving to shammy heals with boomkin - this keeps it interesting for me.

Mostly - it's a game - have fun - do whatever rocks your boat!
