Feral Spirit doesn't really need a lot of discussion. You summon ghost wolves. If you've been to Hyjal, you've seen Thrall and his ghost wolves. These will probably be less cool than that, but along the same lines.
Spectral Transformation, along with the ability to instantly drop into Ghost Wolf from Improved Ghost Wolf, will have PvP utility as a means of escape. But it will also make our summoned ghost wolves from Feral Spirit a lot harder to stop, being immune to stuns, snares and movement impairing effects as well. No fear resist, but that's what Tremor Totem's for I suppose.
Also worth mentioning are Improved Stormstrike and Static Shock. A reduced cooldown on Stormstrike seems like a no brainer, but I'm on the fence about Static Shock. I mean, with all this new spellcasting going on, will we be able to forego the mana regen of Water Shield in order to get use out of this talent? We'll see, but I'm leery.
It appears to me that enhancement shamans will probably need the int they're getting on mail (and using talents to convert to attack power) and perhaps even MP5, what with all the new spells they may well end up casting. Ghost Wolf, for instance, will now cost 13% of base (not modified by gear or buffs) mana, and if you're weaving instant cast lightning or lava into your DPS rotation with Maelstrom Weapon, you can expect to need more mana. All in all it looks like a well designed synergy between new itemization and new talents to me.
