Aimed Shot is changing significantly anyway, closer to what it used to be - used as an opener and then as an occasional proc.
I know these are in many cases nowhere near finished, but given that, I'm not sure of the point of revealing them in this form. When they announced this new format, they indicated that it was completed as a system, but obviously the trees and abilities won't be balanced until they've been beta tested. But they also said the point of this new system was a) to simplify talent trees (fine, they've done that) and b) provide players with more meaningful choices. That really doesn't seem to be in evidence in these trees. It's pretty clear from looking at them that "optimal" specs - ie, take these talents or you fail - will still exist. In fact in some cases, particular specs (affli warlocks I think was one example I tried) require the player take a point in literally every talent (or every talent that isn't obviously pvp-oriented in the case of ele shamans) in the tree to get to the deepest talent. That might change as the trees are balanced, fine, especially if they make it so you don't need five points in a tier to reach the next one. But the idea that players will be presented with meaningful choices for every talent point seems to have been forgotten so far. Of the specs I looked at, from classes I'm familiar with, only fire mages left me having to make a choice between two equally useful or attractive talents.
That might change - I really hope it does - but even so, it's a bit of a let down not to see this new design aesthetic applied from the start.
