I'm not sure what you mean by fluidity but if you mean using more individual abilities then thats down to your macro setup. For questing you will find that the extra FIREPOWER is not really needed unless you are fighting elites or groups of mobs then things will feel a little more fulid and team-like, for grinding you probably dont even need totems. If you can team with others and do instances you will find the combination a little more exciting maybe.

I run a mixed team and it's pretty much, drop totems (q) Pally pull multiple mobs , concercrate / dps spam (1) get aggro Mages Fostbolt and shaman lightning, Mage Priest AOE (arcane explosion I'm still working on Blizzard but screen jumping is a little slow so I need more practice) spam and shaman drops Magma totem (2) evertything dies rinse and repeat.

I imagine things are dieing very fast for you also.

While dual boxing a lock shaman combination it also felt like a healbot because normal mobs die so quickly many of your abilities are not needed. Try pulling groups of mobs, Melee types, you'll find that it's more fun and you will have a better feeling of synergy between you toons. Shaman sets up and warrior pulls them back to the camp or just rushing in and blaze them where they stand.
