The odds of intim shout not breaking on damage, are roughly equal to that of you soloing c'thun, at least in my personal experience. Psychic scream does not break very often. I don't consider the paralyze, a huge bonus, I suppose its nice for 1v1 in PvE so your target doesn't run into mobs. But you omitted a very important part. Cooldown. Psychic scream is on a 30 second cooldown. Intimidating shout's cooldown is 6 times as long.

But as a resto shaman wouldn't you appreciate not feeling forced to sink 10 points in eventide, and mana spring? With the new rank of BoW hopefully the spring talents will be changed so the bought skill is the same as it is with talents now, eventide is de-linked from mana tide. And most of the totem talents are terrible.

I think that's the point though. If any class goes say, 30 points in a tree, and doesn't take the 31 point talent, isn't something wrong with tree design or talents in some fashion?

I'm generally quite happy as a Mage. In all honesty, all I really hope for in the talent review is that they shuffle some stuff around. Anything, really. I just want my character-building decisions to be fresh. Those Priests looked like they were having a lot of fun right after the new trees were announced. Everyone secretly hopes that one day they'll long and things that were mundane will suddenly be novel again, and class changes are a rare opportunity for that. Hopefully the Priest changes indicate that Blizz is getting a bit more comfortable with making meaningful changes, but the "mages are fine" tone they've always had has made me nervous that they won't do very much interesting.

My only complaint about Mages has nothing to do with power level, just with a lack of diversity in good builds. A lot of people try to use interesting builds--I've been trying hard to come up with a tri-spec build for raids--but ultimately you face the decision that if you stray from a few particular choices, you're choosing novelty over pure utility. It shouldn't have to be that way.

Evocation is great example of something that should be made a class skill (more so than IAE). No build without Evo is going to be more useful in raids than any build with Evo. It changes the whole dynamic of the class by removing mana as a limiting factor in a huge number of situations. Imagine if, say, Feign Death were a talent. IAE you can give up and still take your build seriously (though it's a stretch). If you go 40/11 Frost, your decked-out Blizzard is often making itself rather useful while the other mages are casting IAE. Give up Evo, however, and while everyone else is going through their second mana bar, you're sitting there wanding, talking about how you could be using both Fire and Frost spells effectively.

Tactical Mastery seems more like IAE. If you don't spec it, there are ways to patch over that utility in practical situations. It lets you do a few things you couldn't do before, but doensn't fundamentally affect the scope of the class.
