I wouldn't discount the utility brought by Resto Druids. Tranq is still a great throughput CD, and is one of the few raid CDs that can be used while moving when coupled with Spiritwalker's Grace. Symbiosis is also amazing, and Stampeding Roar has many uses this tier.
SL+HTT is way more real utility, and so is paladin Hands, plus CDs, plus Devotion.
Tranquility needs you to have a shaman, use your symbiosis, just to be almost equivalent to HTT, that heals the same, but the shaman can keep healing at the same time.
Stampeding Roar is useful, in very specific fights. And it will never be equivalent to a raid wide damage reduction CD, or even Hand of Protection+Hand of Purity.
Druids also have plenty when it comes to personal utility or survivalbility - Cloak/IB are really useful on many fights (most notably H-Lei Shen), Barkskin can be used to prevent one-shots and Displacer Beast provides you with so much mobility.
Cloak? I think you are talking boomkin not Resto.
Barkskin is only 20% reduction... seriously you want to compare against other healers?
And i agree that displacer beast is great for personal mobility, but every class has a mobility talent.
Mechanically, what exactly is the issue with Rejuv as a raid heal? Unlike other raid wide or party based heals, Rejuv actually gives you the flexibility of spot healing those who need it most.
That its inefficient?
You need to waste 1 sec to place each rejuvenation, you need 10 sec to cover the entire raid, for a total of 87k of mana.
Each tick heals for 23k every ~2.8 sec.
When you finish rejuving the last one, the first is ending.
The problem with reju as raid healing, is that you cannot bring everyone up fast enough.
If you pre-hot you will overheal like crazy, and will OOM, if you wait to heal when damage happens you will take to long to help, and the other healers will top the raid meaning your hots will only overheal.
For HoTs to be useful, you need them the entire time on the target, so that as soon as he takes damage the hot heals, and they need to be VERY efficient mana wise, to worth doing so.
Right now HoTS are expensive, and inefficient, if you wait people to take damage so you can hot, you are in fact doing 23k of healing / 8700 of mana, because the target will be topped before the hot can do its second tick.
Give us Prayer of Healing, or Holy Radiance+LoD for example, and see what we will be using when raid takes damage, those aoe heals or Reju...
AoE heals are VERY VERY efficient when they heal 5+ targets.
Go look at each one of them, its absurd how much HPS they produce, and how little is the HP/M. Our super efficient heal is tied to a CD, and was nerfed to the ground on Cata and never recovered.
The fast, direct heal for every other healer is also rather inefficient and mana consuming. Most of them don't heal for as much as Glyphed Regrowth does though.
But other healers have more efficient ways to deal with tank damage, like beacon, penance + shield, etc... we only have hots that are useless against spiked damage, and Regrowth.
Haste past your breakpoint is a bad stat, sure, but you still have a highly viable option with Mastery.
You cannot reforge everything out of Haste and Crit, so you lose stats as gear improves.
Your mana issue will be addressed with better gear, and you'd find yourself hard pressed to go OOM once you obtain the legendary meta. I agree that Clearcasting may be RNG, but it's still free healing regardless.
No its not free healing when most of the time its overheal just to reset lifebloom timer because clearcast will falls off and there is nothing to heal at that time.
This is true for every non-absorb based healer. As for your specific example of Jolts, using Tranq to top off your raid before the Jolts works really well.
And take the silence? =X
Topping everyone will result in people dying because of Fountain, or swap near the same time.
Other healers have CDs they can use to save the raid. We can only top the raid, reju some people and pray the gods of RGN that everything ends up ok.
Crit isn't particularly good for many classes too. I understand that Haste is useless paste the breakpoint, but what exactly is wrong with your Mastery?
When gear increases you will fatally be unable to reforge enough haste to stay at 3043, and you will always get some crit gear, and you cant reforge 100%, meaning when your gear improves you gain less then classes with 2 good secondaries.
