I'll be going with this

I know it's not the best for mana efficiency (regen) but the damage and CC talents were too much to pass up besides with water shield in PvP it should be fine ^^

Also I've been thinking of a little trick to use on melee Drop ur Fire Novas.. wait till they go off (does damage and applies that slow debuff) and then thunderstorm them away.. they will be 20yrds from you and slowed

btw I want to point something out to anyone interested in Ehn raiding or suchlike

This Spec looks like it's going to be absolutely insane for dps

basically the 3 spells you will need for this spec are.. StormStrike, Flame Shock, and this new Lava Burst..

Thie idea is you start melee dpsing with SS, then shock with flame shock (you will have probably crited in melee, therefore you shock only costs 30% of it's base value), so now you have your flame DoT on the mob.. and you need only to wait until you have 5 stacks of Mealstorm Weapon, for an instant cast Lava Burst (high damage fire spell)).. what happens next is even better ^^..

Lava Burst has a condition that means it has a 100% crit chance against a target that has the Flame Shock dot on it (it will be consumed tho). when you crit with Lava Burst, you Elemental Devastation will proc (9% crit for 10 secs), which means your mealstorm wep loads up faster, and you can cycle those 3 spells over and over, maintaining an extra 9% crit whilst you dps..

An additional bonus is that Blizz are combining melee and spell hit, as well as melee and spell crit rating from your gear, so your shocks will have a higher chance to hit and crit, even from your normal gear

so basically, we are looking at a permanent 9% crit, and on the fly high damage spell crits (courtesy of Elemental Fury)

EDIT: comment on posters spec above me: do you rly want the 0.5 secs off Healing Wave? 5x Lesser Healing wave tends to heal most of my team up quite nicely.
