First off, I like my priest. My attitude reflects my concern about the continued raid and PvP viability for priests (and holy priests in particular) ... not my disdain for them.
The Holy tree in particular is seen as a problem in WotLK. The added talents give us no new mechanic, and simply appear to address some problems that 3.0 will create. For example, in 3.0 there will be a penalty for downranking -- which was a fundamental holy priest tactic, particularly in T6+ content when stopcasting could be perilous. To address this, talents have been added to reduce the penalty for overhealing while fullcasting. So, I would say that many of the 3.0 talents are compensatory, rather than evolutionary.
But my conclusion is that there is no new mechanic for holy priests in WotLK.
While Blizz has argued that some abilities seem "class defining" and that they just don't feel right passing them around to other classes (eg. no more instant ghost wolf form for shamans), healing appears to be a different matter. With each new expansion, the defining value of a priest has become more and more diluted. In TBC, the priest was demoted from being the best single-target healer ... and it took until 2.2 to get an AoE heal that made priests competitive with shamans for AoE healing.
In 3.0, every healing class will have an AoE heal. As the numbers stand currently, the priest's is inferior to all of them. Although, in the current beta, the druid appears to be the only healing class needed by any raid, it is almost certain that this will be balanced at some point (probably before the initial release of WotLK). As I compare the range of abilities as well as overall utility, I cannot help to ask why anyone in either a 5-man party or a 10 or 25-man raid would -need- a priest. We have no type of healing spell for which we can claim mastery: we still have no kind of stackable raid utility, and we are the most fragile and vulnerable healing class. Druids, for example, can now do the best HoTs, good burst, better AoE, and now even good retroactive healing while providing superior raid utility with innervate, battle rez, and the ToL buff.
Some excerpts from the WoW forum emphasize these points:
------------------------------------
In my opinion Holy Priests will be outclassed, outhealed by other classes. I will be sure to keep this post reasonable, but here is why:
- Holy Priests in LK have no raid buffs they bring to a raid
- Our hots are very weak
- our group heals are just plain outhealed by Druids group heals with their version of COH
- We have no innervate, our shafowfiend is not reliable for mana return
here is just one example of why a Druid will just outclass us with their new abilities and talents:
- They have direct heals now that are close to a greater heal in size and the same cast time
- They have a version of COH that is MUCH more powerful
- They have innervate!
- They have battle rez and can now rez out of combat too!
- They are the king of Hots undisputed
- They can buff a raid with Gift of the wild
Basically Druids are the new Jack of all Trades, and Masters of Everything when it comes to healing. Where is the holy priest love?
------------------------------------
In the beta, everything is trivially outhealled by a druid. They haven't done a numbers check. Nourish is a one time cast that outheals a priest spamming CoH. Recently one druid did 75% of the healing in a Naxx run. Of course if they left it this way, people would only ever want druid healers. Duh. But they won't leave it this way so don't even pretend it's an issue.
No, the REAL problem is the failure either a) fix crap priest talents or b) give the holy priest any kind of interesting new mechanic.
Paladin's Beacon is simply amazing. Nourish is the greatest AoE heal in the game. Shaman Spirit Link effectively doubles your main tank's hit points. These abilities will all permanently change the way the class is viewed and played. Priests will continue to flash and gheal with most of the new talents principally there to overcome the fact that we can't downrank.
The ground breaking new mechanic for priests in WotLK is stop casting. Welcome to priest healing in 2004. *sigh*
-------------------------------------------------
Of course, the game is still in beta and the coefficients and the numbers are in flux.
But what you can say at this point with certainty is that every healing class has been buffed with new healing mechanics -- except priests. The position that classes may have defining abilities apparently does not apply to healers, with the possible exception of druids. And that in the current beta, priests have a deficit in the healing:utility ratio. While players of most other classes are looking forward to 3.0, I find that -- at least as a holy priest -- I don't have anything really new to look forward to.
It may be Blizzard's expectation that the buffing of Discipline to a level of raid viability should be balanced by a decrease in the raid viability of Holy.
