Zee MoP Talent Calculator has been updated today. The big change is that the Mobility tier has been taken out and some tiers have been shifted around. The "control" tier of roots and knock backs has been moved to Tier 2 and has seen Repulsion Totem replaced with Windwalk Totem from the lost mobility tier. Tier 1 is now the defensive cool down tier which remains largely the same, some numbers have been shifted around, but most notably Stone Bulwark Totem only regenerates to about one third it's initial drop value every 5 seconds now.
Tier 6 can now be found at Tier 3, but Elemental Harmony has been given the chop which makes me sad. In its place is now Call Of The Elements: a 5 minute cool down that resets your totem cool downs. Which could make for some interesting Elemental usage in PvE, but is nowhere near as useful as being able to drop Stone Bulwark Totem and Earthgrab, and Tremor all at the same time would've been; perhaps why they shot it. Following that, Totemic Restoration now no longer restores totems but, instead, simply reduces the cool down on them by half the runtime time that would've been remaining when they were killed - up to 50%. Totemic Projection remains unchanged.
Tier 5 is now Tier 4 and sees the same abilities in place but cleaned up to make more sense. Elemental Mastery is now straight 30% haste for 20 seconds and no instant cast; turning it into a mini-Heroism/Bloodlust on a 2 minute cool down that actually does something for us now. Ancestral Swiftness, if I'm reading it right, now provides a constant 5% melee and spell haste passively while also acting as an instant cast cool down on a 1 minute timer. Booming Echos remains the same and I suspect the question in the damage tier comes down to this: do you need to burst down targets at specific time windows (think Spine)? EM. Then wait for the math folks to sort out which of BE and AS works best in fights that favour more consistent output over burst.
Closing things out for the moment, as Tier 6 is currently empty, Tier 4 now becomes Tier 5 with no significant changes that I can see.
Two other things are worth mentioning as the spell tree also got a bit more fleshed. Firstly, there appears to be no plan to replace the Haste Totems at the moment. Instead, it looks like all Shaman will be bringing 5 straight up Mastery points - not rating: know the difference - to the raid via a new ability: Grace of Air. All Shaman also will currently bring the Wrath spell power buff via Burning Wrath. Secondly, our level 87 spell has been added and is apparently a transformative ability called Ascendance on a 3 minute cool down lasting 15 seconds with different effects/forms for each spec. We only care about one of those here: "While in the form of an Air Ascendant, auto-attacks and Stormstrike deal pure Nature damage and have a 30-yard range."
Now that will make bosses with zone clear mechanics a bit more interesting, won't it....
