Here we go again..

The current nature of the shaman spec is that mastery is part of the damage of a spell. If you say hardest hitting ability (which is elemental blast buffed by unleash elements) then you have to factor in the chance to overload (e.g. if a spell hits for 100 with a 50% chance to overload for 75% of the damage then the actual spell deals (100+100+75)/2 = 137.5 damage). Either way if 8x elemental blasts don't kill a target in 1 shot, then you are extremely unlucky that not a single one overloads. or you are doing something wrong gear/stats/rotation wise.

Yeah with 8 shaman and unleash elements you should get darn close to a 1 shot with lava burst without overload. Without overload, probably not unless you are pulling over 50k lvb which is about 30%+ pvp power.

Elemental blast is kinda lame, but it's something when LVB is on cooldown and you decide you don't want the super elementals. But it has a 12 second cooldown also. You'd expect something like chaos bolt.
- It is not affected by unleash elements
- Has no guaranteed crit or any other interesting mechanic. Shaman fully geared have.. get ready for this - 10% crit (unless you're not reforging any of it and reforging haste back to crit)
- The buff is random to a stat; it doesn't prefer your highest stat, which is irritating

The primal elementals have issues too. They're awesome when they're up, hit decent, stun, annoy the hell out of people, etc. but when you start doing your round robin tremors, guess what, bye earth ele because I dropped a tremor. Fire eles are decent though and you shouldn't have a fire totem overlap.

About the only shaman thing that hits decent right now is Fulmination, but it also has no special crit mechanic, and it's a proc. I've been doing a lvb, lb, earth shock sequence for kills because at least one shaman is gonna get some nasty 60-80k fulmination. You can occasionally get lucky and 4x earth shock a guy down to 30% right off the bat. Then you got no flame shock up though
