Need suggestion pleaseFollow

I have finally gotten a decent set of gear, but here's my concern.
I have 747 Haste and I am useing Black Magic(250 haste) which procs insanely often giving me 997 haste(almost 31%). Have I gone too far with haste or should I go for more haste? I do 10kdps in heroics and did 13kdps on the 4th ICC boss Deathbringer Saurfang 10man.

I am not sure which diection to go, and I welcome any advice. My gear link is in my signature.

If I am not mistaking the world-couldown on Arcane is 1 sec. So as long as ur casts take longer than 1 second, you can increase ur haste up to 1 sec per cast. (and thats A LOT of haste to go)

I got 1007 haste atm (with hastefood), and still can get another 1000 i guess before I hit the 1 sec per cast.

Correct, a ton of dps but not killing a boss is worthless IMO.

no it doesn't register a non kill, but thats because outside of your guild what happened on a non kill is of no intrest. I'd guess if your wiping at 20% your either popping BL to early and not giving yourself enouhg dps to nuke him through his P2, or your gettting tunnel vision and letting to many adds through, that combined with the mark tends to lead to death.

haste for most class' can be stacked until your fastest cast hits the one second mark. as arcane your rotation is Blast until stacked to 4 and you have a proc, then pop missiles right. with that rotation your missle cast is reduced to 1.83seconds i believe so you could afford 43.5% hastse which would take it down to the GCD of 1 second.

yes in heroics with a shaman when he pops lust pop your cd's and only cast AB you will get 8-10k dps on heroic bosses and they will die in 30sec or less.
you have a lot of hit ration you could totally dump it for more crit/haste you probly dont notice your haste doing that much for you any more your spell takes a lot more haste to make it go down at all so you could look towards more crit maybe, but like they said you can always get more haste till it only takes you a second to cast arcane blasst which you know you cant do so...id ditch the wand first for the one out of toc 10/25man, id also get rid of your neck get the 245 badge one has spirit and haste on it get rid of the hit on your neck.
