From how i see these new talent builds, they all seem incredibly situational. (
http://www.wowhead.com/mists-of-pand...calculator#shm is the talent build i'm thinking of using at the moment)
I like the Stone Bulwark Totem simply of a small shield of damage for 30 seconds which can be used if you are taking constant damage. The Nature's Guardian i see as not really that brilliant due to the fact that it only decreaces your threat on that target and your health pool if you are brought under 30% health, i don't see this as viable due to the fact you have to go under 30% health and more often than not we have no issue with threat or not having enough maximum health.
Also the Astral Shift i can see myself going for in more survival than dps fights so that for example, i could take more stacks of the shard on Baleroc HC.
For the next tier, i have gone for Tranquil Mind Totem as i find in PvE that its less often to have movement reduce effects on you than it could do a raid wide silence so i simply put, went for the Anti-Interrupt totem. The other two are against movement impairing effects directly on you (Improved Ghost Wolf) or people near you (Windwalk Totem).
At the level 60 tier, i have gone for Ancestral Guidance due to the fact that if i were to stand close-ish to the tanks 40% of my dps would turn into hps so if i were to typically do 30k dmg on a boss i would be doing 12k hps to a nearby tank which would be very beneficial for the healers. I could have also gone with the Healing Tide Totem which would basically do 5k healing over 10 seconds to nearby targets, which would be good for AoE fights say when Smoldering Devastation is being done on Beth'tilac HC. The other talent to chose from is when people were standing in healing rain they took 10% less damage from magical attacks, i see this being mainly the healer choice out of the three adding another defensive CD, however if there is high AoE magical damage i can see myself swapping this in and out to suit ithe fight the best.
At the level 75 tier, a shaman can chose from a cooldown giving one instant cast 15% damage increase and 20% spell haste for 15 seconds i see this as more of an Elemental talent due to the instant cast and spell haste which Enhancement would have little use for but depending on how the other talents (which i will move onto in one moment) play out. Nature's Swiftness is quite nice due to the free instant cast of a baseline of 10 second (maximum) spell and a passive 5% melee and spell haste which i would link a lot more closely to be viable for elemental due to the passive haste and maybe a free Lava Burst. The last talent is the one i've chosen which is the Echo of the Elements which is essentially Elemental Mastery at the moment, and i see this as the best choice for Enhancement due to the fact of (i'm hoping) that the Echo could maybe copy Windfury Weapon Proc of maybe even Lava Lash? Which would be fairly strong.
At the last tier, a shaman can pick Elemental Harmony, Totemic Restoration and Totemic Projection. Elemental Harmony allows for a shaman to pop more than one totem per element so for example of the current totems: Tremor and Earthbind totems at the same time. It is worth noting that Blizzard said in one Q&A panel that this would not apply to fire totems which is what made me go away from this talent. Totemic Restoration i see as more of a PvP totem for when, say and enemy tries destroying one of the cooldown totems, like Stone Bulwark Totem, but besides Majordomo Staghelm, i have not met a totem-hating boss so this isn't optimal really. Totemic Projection i have chosen due to the fact that Enhancement, as a melee dps often has to move around a bit so just throwing the totems somewhere else would be viable such as when moving between the two location for dealing with Ragnaros HC's seeds.
