(not playing classic) but I'd go with Mages, your ability to handle mechanics makes you much more versatile for more scenarios. You also have an out in Ice Block for a complete immunity if you mess up a mechanic. I suppose mechanics in Classic aren't as in depth as retail but it still catches up the more it progresses.
The other part was gearing them out. Mages can work with more and their power curve is more forgiving as you gear up.
