Shaman
I checked the shaman first because I play a shaman main. I wanted to check to see if the level 90 talents were in, and by golly, they were! Our premade characters were only level 85, so I couldn't test them out, but I did write 'em down for you.
One supercharges your Unleash Elements to provide a much better bonus for each imbue type.
Another removes the cooldown on your Fire and Earth Elemental Totems and allows you to control them.
And the last is a blast of elemental energy in a cone on a 15-second cooldown.
Bear in mind that talents are still being worked on, and these may not be final. I also may not have remembered the nuances of each. We couldn't take screenshots, so this is the best you'll get until Blizzard updates the talent calculator.
Also of note: Totems are no longer listed as separate spells in your spellbook. There's an expandable button for each kind of totem, and you can pull totems from there if you want to put specific ones on your bar.
