I dont get what more lets say Resto Shammys have against burst? Totems? Nuked down in 0,5sec. CDs? I say druids have better. Ghost Wolf? Druids have better. I think almost any healer suffer alot from burst, pallys can bubble but that only gives them seconds against comps which can break it.
That's not even including wind shear to stop any sort of offensive cast at them.
The problem about shamans kick immunity is that a single dispell will kill it, as soon as you dispell spirits walkers grace the immunity is gone aswell. So it isn't very reliable at all if the enemy team has ANY class able to purge. Also while trained by the melee pain train you are not going to get off a while lot of heals. You're talking as if all these melees have no interrupts (some of them several), stuns, fears and other stuff to interrupt a Shamans spell casting.
The only thing that is nice is spirit link totem, but even that requires your team mates to actually run to you and get very close thus making them easy targets for CC. Also it can't be used while in any kind of CC or silenced for that matter and can be destroyed.
I currently have all 5 healers at 90, and I personally think that they go like this:
HPaly > Rshamy > Rdruid > MWmonk > >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Disc
Hpaly and shamy are interchable, they are pretty even but i think more ppl are rolling shaman. Rdruids are good until they have no CD's then they die too easily. MWmonk is THE BEST as far as mobility. Very difficult to hold them down so mele cleve comps have troubles with them. but with a vast majority of their spells being cast while channeling soothing mist (an 8 second channel) vulnerable to interrupts a lot.
I wasnt even going to include disc, but its an option (but not really) very little CD's and not a lot of viability, stun=death
So many disc haters, disc will be fine passive 30% damage reduction, the way rogues are on ptr and well mages expect rmp to be a really strong comp
Kind of sad that Disc being good is based of a comp. Paladins and Shams have a niche but can fit into anything...
I kinda suspect you never had a DK and Warrior train you, because in all honesty both earthgrab and ghostwolf will do very little to help you very little when trying to get some distance between you and them. And it's not as if both of them are able to solo drop a target within seconds when popping cool downs much less when they work together.
The only chance for most healers to survive on the long run in the current environment is through a lot of support from their DPS. Because having 2+ DPS on you will do you no good, especially with the current melee and some classes such as ferals completly ignore the defenses of several healers.
The CC nerfs are going to hurt pally alot. Not being able to insta blinding light mellee off is going to hurt pallyies alot. Don't get me wrong its justified, but blizzard are going about it the wrong way.
Only 3 of my healing spells are castable, and I really do not use them that much. Then they are buffing our damage which will increase our healing for fistweaving so we even will have more instants we are able to depend on. Soothing mist is okayish healing, Surging mist mana regen sucks and we have way more better skills to use besides that enveloping mist is okayish.
Rsham or Rdruid
