In my opinion specs like disc should be at the absolute bottom of the healing meters. Bringing a disc priest is like bringing half a dps to the raid. I think they should decrease the mana cost on mass dispel make it disc only buff up spirit shell and either make it a 3 minute cooldown or link it to all of their healing to make it absorbs just to be different. In my mind disc should be a utility spec giving them the best of both worlds is one of the stupidest things I could think to do to a game like this. If you did that you could buff up Holy to a competitive level and give priests the choice of raw healing or Utility. I Think Disc would be a lot more fun if you added a few other things to it then smite spam with the occasion holy fire PW:S and a few heals everytime the spirit shell CD is up. I also think that Priests would dual spec more were that the case. I would Make Holy mostly stationary healing spec and make it pump out awesome numbers. I think resto druid and holy priest should trump everyone else on the sustained healing and fall back in the shadows on the utility.
I think Holy Pally is pretty ridiculous right now. I saw a very small illuminated healing nerf on the patch notes. In my eyes they may be the most OP healing class of all right now. In PVE Raw healing I get beat way worse by the pallys than the priests. Holy pally should be a highbrid of utility and power. Bubble, BOP, Sac,Salv. Along with plate and shield a full compliment of stuns less interuptable damage in pvp. Right now I would rank pallys as my most hated In both Pve and pvp except when I get beat by a disc priests doing 60k dps.
Monks if I'm not mistaken do a bit of damage in their healing. I'm honestly not too familiar where I think they should fit in. They seem to be in a pretty good place as far as being able to bomb heals and Mana tea back up. The only real experience I have with them is fighting them in arena and hearing my gladiator SA yell at me every few seconds about them using mana tea.
I think Shaman look fun as hell right now. All about the Utility and clutch heals and cooldowns. Once they get back to where they need to be and they have been getting a lot of love lately They are gonna be awesome. A reverse of the utility brought by something like a disc. Not the raw healing power of a druid or a pally but with those healing cooldowns that can save a raid like nobody else.
Now to druids. The Mobile heal spamming constantly casting we bring a few goodies to the raid. Not to the extent of any of the other healing classes we are actually kind of a drain on the other healers. We bumb innervates, Mana tides, Hymns and anything else we can think of for mana batteries. If it weren't for absorb healing we would be the straight up healing gods of this game. Able to push the numbers as far as we push our mana. We have good can survive very well off of personal cooldowns but our gift is in our sustained healing and as the game sits our overhealing. Shamans may be the most underpowered but I think we are furthest from what I see as our niche roll.
Now these are purely my view and my vision for the game. If the devs saw things like I do the fixes are fairly simple. Things like integrating the healing strengths into 25s or picking the right make up for 10s could prove to be a really fun challenge. As it sits though you have A few classes that sit way up on a pedestal and the rest of us in obscurity wondering when somebody will fix the broken game.
