posting a big list means nothing. Let's pick out any changes that affect resto and discuss them, shall we?
Chain Heal's effectiveness has been increased by approximately 10%. - a buff, but still not enough to make it into a regular rotation at currently viable levels of haste.
Healing Rain now has a 40-yard range, up from 30, to be consistent with other shaman heals. - not a buff or a nerf, basically an oversight on Blizz's part. For the most part you shouldnt be over 30 yards away from someone you're supposed to be healing anyway.
Spiritwalker's Grace duration has been increased to 15 seconds, up from 10. A slight buff, but for a very situational spell.
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. - a pretty big nerf for PvE shaman.
Cleansing Waters no longer fires its heal effect twice when a shaman removes a Magic and a Curse debuff with a single cast. - A nerf of a bug
Deep Healing (Mastery) has been increased to 3% per point, up from 2.5%. - a buff to mastery
Greater Healing Wave mana cost has been increased by 10%; healing done has been increased by 20%. - a buff to GHW that by all numbers I've seen still doesn't make it surpass a TW buffed HS, unless it's used with UL.
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. - Huge nerf.
Buffs - 4. None of them are very effective, in my experience. CH is still a back-burner spell for me. GHW is still behind HS for me. Spiritwalker's grace lets you get off 2 more casts while running, but why are you running for 15 seconds anyway? The mastery buff hasn't shown any big difference for me yet, but is probably the only change that is a pretty decent buff.
Nerfs - 3. The MTT nerf is huge, there's no way to sugarcoat that. The Tremor totem change is stupid, but not really important for a raiding shaman. The cleansing waters nerf is not that big of a deal.
So unless you think those buffs greatly increase throughput (which they don't seem to be according to experience and the logs so far after 4.0.6) then that 'huge long list of buffs' is pretty much equal on buffs and nerfs for resto shaman. We come out even, while all other classes come out even or ahead. We were already way behind. If Disc priests could get a significant buff to bring them closer to the other healers, why couldn't shaman?
