Now that they've changed the
Relentless Earthstorm Diamond (+12 agi, +3% crit damage) to apply to all forms of critical damage and not simply physical critical damage, would this be a viable metagem for an elemental shaman?
Take average stats for a moderately-well raiding ele shammy, and you should have around 33% chance to crit with lightning bolt. Say their lightning bolt hits for a average of 1.8k, that'd be a crit for 3.6k. Has anyone been able to figure out whether this would add 1800 * 0.03 = 54 damage to every crit (making it equivalent to ~20 spell damage) or whether this would add 3600 * 0.03 = 108 to every crit (making it equivalent to ~40 spell damage)? If it's the latter, this would be a monumental gem for ele shammies. Especially considering the only other good options are +12 spell damage/minor run speed, +14 spell damage/5% stun resist and 14 crit rating/1% spell reflect.
