Crit does nothing for Lava Burst, which is 35-40% of our damage. In addition, it does nothing for the dot component of the Flame Shock. It does help with Lightning Bolt, Chain Lightning and the initial hit of Flame Shock or our Earth Shocks, so basically the stat is useful for half of our damage and useless for the other half.

Haste is similar. Lava Burst has a fixed cooldown period no matter what our haste is. Our Thunderstorm and Shock spells are all instant cast, and haste does not improve the dot portion of the Flame Shock. Haste is still a good stat for Lightning Bolt and Chain Lightning, but its probably less useful at level 80 then it was at level 70.

Spell Power is our primary dps stat for pvp. For pve, once we're hit capped it's our primary stat, but until we're hit capped its our second stat.
