This entire post is completely hypothetical. A thought experiment, if you will.
The Raid and Dungeon forums are currently in an uproar over the slated nerf to Windfury Totem. It is a general consensus that Alliance raiding is easier than Horde raiding, and that shamans are less powerful than paladins in PvE. So to nerf Windfury Totem, which is used by Horde tanks to increase rage and threat, seems nonsensical. If you add this nerf to both the shaman and paladin reviews, it almost begs the question, is Blizzard playing the same game as the rest of us?
Well, what if Blizzard isn't?
In all the discussions on the forums, the only items being taken into consideration are blessings, totems, and heals. All other aspects of the two classes are ignored. In a 40-man raid, the player base assumes that there are 15 healers, who stand in the back, buff and heal. Gregthegreat on the paladin forum summed it up best: "A paladin is better than a shaman because a paladin emulates a priest better."
But what if Blizzard does not have that same assumption? What if they assume that there are only 10 or so full-time healers, and shamans and paladins are meleeing/casting and spot healing? And that their raid design takes into account the additional paladin/shaman damage when they balance the two factions.
I think that a lot of Blizzard's actions regarding the shaman and paladin make more sense when looked at through this lens. If Blizzard believes that the existing optimum raid strategy for paladins is to melee, how are they going to react to calls to improve meleeing? I think they would be confused, and make minor changes, shuffling things around. Which pretty much describes the paladin review. After all, if meleeing is already the best strategy, making meleeing better just breaks things.
I believe that Blizzard tests its content, with raids from both factions. That proposed changes are the result of the internal testing. But if the internal testing makes fundamentally different assumptions than the player base, there will be a disconnect between what the internal team believes is necessary, and what the player base believes is necessary.
From my own personal experience, 15 healers *is* excessive for the majority of fights. 10 healers, with additional spot healing from meleeing paladins, is good enough for most fights. And if that holds Alliance side, it should also hold Horde side.
It also explains the Horde/Alliance disparity a bit. A paladin has a low amount of internal power, but gives a lot of power to her allies through buffs. A shaman has a higher amount of internal power, but gives less power to his allies. So if they both restrict their actions, the Horde raid suffers much more from the withdrawal of shaman power than the Alliance raid does from the loss of paladin power.
Now, I don't know if what I described in this thought experiment is true or not. For this to be true, the commonly held wisdom by the player base about raid roles--that paladins and shamans are primarily healers--is false. But a lot of Blizzard's actions simply do not make sense if the common wisdom is true. So we're left with two choices. Either the common wisdom is wrong, or Blizzard does not know what they are doing.
I'm sure I know what the cynical among you would pick. :)
