My point is: Shaman healing is based way too much around CD usage. HTT, HST, and HR make up a significant portion of their healing (HR is probably OK here since there's a significant mana cost attached). I don't see nearly as much Chain Heal (which is a staple Shaman healing spell) as I did back in Wrath or Cata. CDs shouldn't contribute that much healing in an encounter, but they are required for Shaman to be competitive. I think this is a huge issue.
This also brings up the question of how Shaman perform outside their CDs. It may suggest that their output is lacking. This should be a huge concern for the Resto Shaman community.
I could agree with most of this.
If you want to increase throughput in PvE, I'd say to buff Shaman's basic spell coeff numbers across the board, then maybe nerf Mastery so they aren't so reliant on folks dipping low for decent #s. Good luck getting the Shaman community to agree on anything, though. Some of their key abilities can have varying degrees of effects or usefulness depending on whether you are talking about 10s, 25s, or PvP, and it was a big reason for a lot of the crap that occurred during Cataclysm.
As I also mentioned, Shaman is very much being propped up by their CDs and utility because their baseline healing abilities are so restricted. Their CDs and utilities do a lot to negate that weakness. As hypocritical as it sounds after the homogenization lectures, Blizzard might be ok with that: it's hard to tell unless they specifically say something about it. After all, they *still* haven't given CH a proper fix, not to mention the infamous Shaman "revamp" that turned out so mediocre they are trying to forget they ever said anything. I certainly don't expect anything comprehensive mid-expansion after what happened (or didn't happen) during the last two betas.
