Heh, yeah that's the worst thing about DPSing as a fury... you can never go "full out" too often. With often two necros in my group I'm stoping to heal the buggers up for Lifeburn. but I would give you some advice:
If you can melee on a mob drop the grizz mace and get a good Two Hander and just toggle autoattack. That will net you more dps than the grizz procs and as long as the delay is long enough you get most of your swings in and never interupt your spell casting. Pride's Edge (fabled 2Hander from Deathtoll) seems to be perfect for the delay for spirt engored flail (legendary drop in bonemire) is a close second - ideally 2-3s delay is perfect.
If you are going to cast ring opf flames do so at the beginning.. ideally when you are toggling on autoattack; it isn't worth casting it mid fight. you get more dps keeping to other spells.
Next when you get your troub back; spam like crazy in Maestro but do NOT use the group heals (for infusion) - use the irritating swarm (group debuff - I use the level 45 one

) instead Maestro won't proc orff a proc but it would proc off your irritating swarm and turn it into an AoE nuke :-).
Plus give Vim to your Troub; the procs work off their intelligence so giving them more is only going to help the raid and your dps in particular. at least I'm pretty sure it does... they keep changing this :/.
As for dispatches... if you have two brigs in the raid ignore the dispatch messages- it'll be up most of the time so just go full out all the time. If you only have one brigand try and time your vortex to dispatch and you'll start to see those 8-10k thunderbolts coming in. I've never hit 10k myself but I'm getting there

.
I only see one master smite... try and get all your L&L finished and bascially use it as another nuke it hits for a fairly decent amount as well as working as a conduit to proc all your gear

Infusion may be great to use but it won't proc anythgin as it is already a proc already so its best to use a damage spell than infusion.
Your crits do look a bit low but you're missing your troub so all depends what it is like when you get back. I think I run with 45% spell crits in the raid and it does show
Lastly if you're not casting you're loosing dps so spam spam spam. sometimes when everything is on recharge I fire of Thermal Shocker... and have seen that crit for 700+ each
Anyways... that's my advice. if you take anythgin from that try it out

I can maintain about 1.2k-1.7k when I can go full out with infusion toggled on. Obviously it drops rapidly when I have you.... you know.... heal :P
