For me...
1 - heal
2 - 70 slow
3 - new slow
4 - XXX at the Moon
5 - Feralgia
6 - Fero
7 - Poison nuke
8 - Maelstrom
9 - Frozen XXX
10 - New Ice Nuke
11 - Old Ice Nuke
12 - variable (generally pet heal)
For raids I swap out #2 to the new pet rune, and #12 to a dot. I have a couple spell sets that will swap that last spell gem out w/ haste, SE, etcetera (so all I have to do is type "/mem haste" for example).
My setup works well with multibinds -7 through 12 are all set up so I hit Ctrl-~ and it casts the first one up, and this order works well to front-load dps but starts cycling w/ Cyanin quickly so my total # of casts is solid (i.e. every 2 seconds there's something to cast for a good while). It leaves the manually-cast (via Alt-1/2/3/etc) spell gems close at hand for me as well.
For yours...
Dots are of poor utility in groups, I'd replace it w/ the previous ice nuke.
Growl is redundant since you have Feralgia up.
Haste is only used every hour, so it's taking up a slot you could probably use for something else
Emp. Warder - I'm just biased against this spell still, so I don't keep it up.
