We have a decent mix of specs. Before 1.11, none of us have mana tide. Now, I think we have 2 or 3 shamans, myself included, with the talent. We have some 21/0/30s, some 30/0/21s, some 0/30/21s, some 8/13/30, and more, I think.
Yeah, it's hard to really fuck up your spec too badly as a raiding shaman. Get 5/5 Healing Focus, get 1/1 Totemic Mastery, get 1/1 Nature's Swiftness (so 21 Resto). Anything else you do with the other 30 points will be just fine, really.
I also took healing way, but I am not so sure I like it. I think Blizzard wanted to encourage shaman to do more than cast LHW and occasionally chain heal, which I am down with. I took the -5 talent on healing wave, and I use it almost exclusively on tanks now. I guess my problem is that I'm not sure I cast enough healing waves on a target in a 15 second span to make the talent worth it. And while it affects other shaman's healing waves, I have an inkling I'm one of the few in my guild who's actively trying to mix healing waves into the LHW spam.
I also took ELE up to that resist talent, but I'm not sold on that one either. Sure seemed like a good idea, considering how important resist gear is during certain fights, but I haven't really noticed any difference.
Seems to be one of the better "pure pve" builds. I originally had the healing way talents, and the Improved Healing Wave, but I didn’t use healing wave enough to justify 8 points. Threw them in ancestral knowledge and tidal mastery and never looked back!
When pve becomes less of a focus for me, I will probably spec something like this:
I was slightly disappointed by healing way since +healing doesn't affect it. Now it's just a focused version of purification which works with only HW. I think I'm the only shaman in the guild that has the talent though so I'll probably keep it for a while.
Edit: For clarification, the numbers in the D and E columns are theoretical while B, C columns have actual numbers.
The sample size is not large so the results might not be entirely conclusive. But from what I found, Healing way seems to work exactly like Purification. It's a flat +% to the base spell and doesn't use +healing with the multiplier.
Actual numbers are a lot closer to
[(Avg. HW) x 118% + healing coeff. + 5/5 Purification coeff.]
[(Avg. HW + healing coeff.) x 118% + 5/5 Purification coeff.]
