So you're saying that I could make it so Lava Burst, Chain Lightning or Lightning Bolt don't stop casting when I move? This could be absolutely huge for casting spells in high avoidable-damage situations. Imagine Defile is about to cast and you know it. You hit Spiritwalker's Grace and you can run away without losing that Lava Burst you're casting. Sure, it'll be huge for healing shaman too, but frankly this ability will solve one of my biggest problems with elemental as a playstyle: all the damage you lose jumping out of things. The longer cooldown means this'll be a situational ability as opposed to making you an unstoppable chain-casting machine, but the 10-second duration means you'll have plenty of time to get a few casts off before it ends.
There's more, though. Much more.
This is arguably the biggest change for elemental shaman in this announcement, and one we've been asking for for a very long time. We're currently restricted in which fire totem to drop -- the one that provides the group buff (Totem of Wrath) or others that directly help our DPS (like Magma Totem). This change removes that problem completely by allowing any fire totem to provide ToW's spellpower buff. It also solves the problem of demonology warlocks providing a superior buff without having to make a DPS-or-buff decision by making the fully-talented totem a 10% spellpower boost instead of a flat increase. We asked, Blizzard answered.
But what about the crit bonus that Totem of Wrath currently provides? I don't see it mentioned here. Ominous!
This basically amounts to a shaman Judgement, but I care not -- these sound great for all three specs. The elemental one in particular has both a direct-damage component and a huge boost for our next Lava Burst. With the ability on 15-second cooldown, you could feasibly boost every other Lava Burst you cast by 20%, effectively increasing your total Lava Burst damage by ~10%. Not an insignificant amount. Obviously there's theorycrafting to be done as to whether using the GCD -- if there is one -- for Unleash Weapon is worth not casting a Lightning Bolt, but that's for another time. For now, I'll bask in this awesome buff.
A small but welcome change.
Another fantastic addition. Elemental shaman suffer from lackluster AoE capability: our most powerful AoE spell (Magma Totem) is incredibly expensive and requires us to be right next to the mobs we want the totem to damage. For a ranged class, that's rather silly. Earthquake should let us become competent DPS in group situations.
Of all of our current elemental talents, Lightning Overload always felt the most ... elemental, I suppose. It was the perfect passive talent -- cool as hell when you got it and useful as a DPS boost 100% of the time. It only makes sense that this would be the talent that got converted into a mastery bonus. The fact that it now works with Lava Burst, especially combined with the Unleash Weapon: Flametongue ability Blizzard announced, is a welcome and wonderful change. What does remain to be seen is how the proc rate will work -- right now Lightning Overload has a very high proc rate, and it's a not-insignificant chunk of our DPS. Changing LO to a Mastery bonus could mess with this paradigm, though I'm sure Blizzard has thought of this already.
I am a little concerned about the second-tier bonus, though -- crit has always been kind of a second-banana stat for us, due to Lava Burst being a guaranteed crit, and so far there haven't been any changes announced that'd make it more useful. Haste seems like it'd be the obvious choice for a mastery stat to me. We'll have to wait and see what else is up Blizzard's sleeve.
