Patch 4.0.6 and the Resto Shaman

Some things changed for us in this last patch so here's a quick breakdown of what affects us and why it matters.
There are notes that have been omitted. I only included those that directly affect restoration shamans. For the full patch notes check here for the full patch notes.

• Chain Heal's effectiveness has been increased by approximately 10%.  - Much needed! Chain heal, one of our signature moves, was sitting around collecting dust.
• Healing Rain now has a 40-yard range, up from 30, to be consistent with other shaman heals. - It's nice but not omgwtfbbq awesome.
• Spiritwalker's Grace duration has been increased to 15 seconds, up from 10. - A lackluster talent made a little better. SWG is too situational and an extra 5 seconds doesn't make up for the fact that it's a lame talent.
• Tremor Totem has been redesigned. The totem is now usable under Fear, Charm, or Sleep effects, and pulses much more rapidly, but lasts 6 seconds and has a 1-minute cooldown. - Tremor Totem was fine the way it was. It was a nice little insurance policy that shaman's carried with them. The constant pulse was far more useful without being overpowered. I think as of right now Shamans are probably the least desired of any class in a raid build and losing unique tools like Tremor Totem and Heroism has gone a long way to this end. I say boo to this change.

Restoration

• Cleansing Waters no longer fires its heal effect twice when a shaman removes a Magic and a Curse debuff with a single cast. - That's fair. It shouldn't have done that in the first place
• Deep Healing (Mastery) has been increased to 3% per point, up from 2.5%. - Buffing mastery doesn't make it any more desirable a stat thanks to it being useful only in a handful of circumstances.
• Earth Shield can no longer be dispelled. - Doesn't impact us from a PvE standpoint.
• Greater Healing Wave mana cost has been increased by 10%; healing done has been increased by 20%. - This is an excellent change. Now GHW can go back into the arsenal and do what it was designed to do: Take a long time to cast, drain your mana, but put a big ass heal on your target. Bravo Blizz!
• Mana Tide Totem has been redesigned. The totem no longer multiplies the Spirit of those affected by it. It instead gives a flat amount of Spirit equal to 400% of the casting shaman's Spirit, exclusive of short-term Spirit buffs affecting the shaman when the totem is dropped. In addition, its effects are now raid-wide. - While this does stop us from abusing the spirit trink/MTT drop we had to see this coming. We could almost break the mana conservation mechanics with correct trinket and totem management. The raid wide thing is nice too.
