To be honest i ment that as a troll =D but i suppose i'll do the best i can to help you.
I'm not the best ele shaman out there and my knowledge is a bit out of date, so if brightleaf comes in here and tells me i'm wrong listen to him.
I don't know if Gold is an issue for you or not, but i would suggest dropping Jewlcrafting for any other profession, however blacksmithing i currently the top profession. Swapping Jc for BS would be a large gain in intellect alone.
Near the end of last tier shamans where starting to move away from haste and into mastery, and with this tier's set bonuses i beleive mastery is almost even with haste (correct me if i'm wrong).
In short what i'm saying is you need a little more mastery, lets look at your uptime on Time Rupture from the first parse you listed to us (
http://www.worldoflogs.com/reports/rt-f ... 398&e=9703). As you can see it's about 51% (50.6% to be exact).
Now lets look at brightleafs uptime on Time Rupture on his top ultrax parse (
http://www.worldoflogs.com/reports/rt-u ... 512&e=5857). It is 74.6%. As you can see that is a drastic diffrence, for 23.3% of the fight he had 750 more haste rating then you.
Because of this he was able to get off 62 more lightning bolts (not counting mastery) in only 39 seconds of extra combat time. (Note this is with LESS haste rating then you have, he is currently running 16.91% to your 17.74%)
Brightleaf also has just over 600 more mastery rating than you, sure some of that is gear, but i would assume some more of it is simply the way he reforges.
Now i don't know what the exact values are for a ele shaman, or if there is some haste point you should be trying to hit, but try changing the reforging on your gear a bit. aim for a 17%ish haste (going by brightleaf's 16.91%) and move all those gained stat points into mastery.
So in short, gain a little more mastery if possible by dropping your haste to about 17%, and if you have the gold, drop jewlcrafting for Blacksmithing.
Try that out next week, see if you have any improvements, i'll tell brightleaf to double check what i said, but in the mean time tell me if that helps out any.
