Drop the Shaman for the last slot and fill it up with a DK?

Zenga can you link me to your armory

http://eu.battle.net/wow/en/characte.../Zënga/simple

and tell me your general casting rotation that you are using?

specced into unleash fury/echo
Searing down, I open with unleash elements, flame shock (glyphed), stormstrike, lava lash, lightning bolt, rinse and repeat with whatever comes off cd, where searing totem is highest priority follwed by unleash elements and 5 stack LB. Pop pets/cds as you see fit.

Edit: I just ran your toon aelli through simcraft (an app that simulates a boss fight) and your dps is 65.730. That is a tank and spank fight, over the course of 450 seconds, a normal target for the hit cap and low lag; assuming all raid buffs and debuffs are present.

If you were to replace your enchants with dancing steel on both your off and mainhand, your dps goes up to 68.728.
Glyph of flame shock increased that dps with another 1.7k.

This is the damage breakdown per execute time from you armory:



Note: I ran only 10,000 iterations, which might result in some variation in the outcome. You can go up to 50k iterations to reduce the noise yourself if you'd wish to do so. (google simulation craft, download/install, under options set what you want, enable/disable debuffs, import from the armory under import, then simulate, fairly straighforward and a great help as you can get a more indepth view of whats going on).

Edit 2:

Ran the dk that looks to be the best geared one and that I found in your 5s team, through simcraft as well: 75.198 dps, under the same conditions. (http://us.battle.net/wow/en/characte.../Ellãy/simple)
