I don't know ... maybe I'm doing it wrong, but with my group (which is identical to yours) my mages are not nearly as glass - but then again I have them as Frost with just enough Arcane to get improved CS. Ice Barrier is great for any time I want to AoE, and Blizzard works great at the same time as my rain of fire. I put up Curse of the Elements and Shadowbolt/Frostbolt spam - since my mages and lock have reduced cast time on those spells they are all in sync - making management of spells a whole lot easier. I may not have the uber DPS other groups have, but I've been clearing every instance I've tried. Also, for boss fights Icy Veins and the elemental make for a wonderful "oh shoot gotta crank the DPS NOW". Am I going to put together a Shammy/Pally group? Sure - but only once I get bored with this group :thumbsup:
