These numbers can't be right. The differences are just too big.
They're pulled from the alpha WotLK client. They may not be what the numbers ultimately end up being, but they are numbers Blizzard developers decided to include in the initial tests of the game.
Kortar, it seems like you're making too many assumptions for the conclusion you're jumping to.
I've tried to avoid anything but the most basic assumptions. But unless you identify the assumptions you believe are false, I can't justify them.
For example, your comparison with shadow priests is off...have you seen the intended changes to Vampiric Touch?
Yes, Vampiric Touch is reduced from 5% to 2%. However, if it was not reduced the conjunction of improved Shadow Priest damage scaling and the rate of improvement on damage vs. mana regen would cause Vampiric Touch to outperform any reasonable game balance.
Also keep in mind that a change in the relative scaling - which is what we're really concerned about - would be likely reflected in the costing of Shadow Priest damage spells since they always have Vampiric Touch as an option.
At this stage of the game (so to speak), it's waaaay too early to be calling this IMO.
I'm not making any claims about what the game will be like when WotLK is released - I can't know that. All I'm doing is saying that if WotLK went live right now, Resto Shaman would almost certainly not be viable healers in a 25-man raid unless there were some fairly radical and unusual changes to core game mechanics.
Regards tranquil air, it's *really* not hard to make it work raid-wide. Just have it not affect people in defensive stance, frost presence, bear form, or with righteous fury up. Ta-da!
It may not be hard, but there is no indication they're going to do this. And if they were going to make this sort of change, they could have made it work for 5-man instance groups long ago.
Also, keep in mind that the original justification for adding Tranquil Air to the game was to counterbalance the advantage provided to Alliance by Blessing of Salvation. Given that this advantage no longer exists, there really isn't any reason for the developers to give Tranquil Air much consideration.
I disagree that resto shaman will be "non-raid-viable." But I suspect you're pretty set in your opinion so I won't try to argue it.
Please do argue it. The point of a discussion about the proposed WotLK changes is to determine how the game will actually be affected. If you refuse to participate in analyzing the mechanics, you're just venting your feelings, not contributing to the thread in a meaningful way.
