Unleash elements is very situational... Even when I play a single toon I barely use it. It's pretty rare after the first Lavaburst that you have Unleash Elements and Lava Burst up at the sametime.

The real problem is that the GCD that it takes isn't justified by the dmg output of the ability. The small amount of damage that it does + the 30% is still less than like a single lightning bolt. I find Unleash Elements best used in pvp, enh / resto rotations.

Pint... My only complaint about your shaman macros. I guess it's personal preferance , but with the amount of CCing that I'm doing in heroics auto chain lightning breaking CC's drives me nuts. Most the time to resolve this obviously just pull the mobs away from the hexes.

The real issue to chain lightning in your rotation like that mana becomes an issue on the longer fights.
