I don't mind being a "support" to a whm. It's nice that the SCH/WHM combination can make a party much more efficient. In my coil group, neither myself NOR my whm ever have MP problems because we're always supporting each other. My shields and tank-focused healing allows the WHM to focus more on group/non-tank heals. This means more up time for stuff like Foe Requiem instead of the DPS hit the bard takes with Mage Ballad.

I know people frown upon FFXI references, but inter-class dependency is one thing I miss about that game. Here in FFXIV, you can pretty much throw together any mix of jobs and everything will work out just fine. SCH/WHM is practically the only job combination that actually sees a dynamic increase in efficiency compared to other job combinations.
