I think you missed the point on this one, lausifer.
Spirit Link's usefulness was already dubious in the minds of all the Resto Shaman on this board, doubly so in PvE. None of us really expected it to do much there. But the one thing we could all agree on is that it would be great for PvP, particularly in 2v2 and 3v3. Not because of the damage reduction, but because of the anti-CC properties. Keeping a team of two or three people CC-free might've made a Resto Shaman potentially worth choosing for a class other than an Arms Warrior or Ret Pally.
Now that the ability is auto-dispelled when a member becomes the victim of Scatter Shot, or Polymorph, or Blind, or any other ability that it would have actually been useful in preventing, it's PvP utility is essentially removed in one fell stroke, and with it, that of Resto Shaman.
There's already no reason to choose a Shaman over a Priest or Druid and possibly even a Pally. Now it's just comical.
