Yes they are...not all 25 change based on your class but plenty of them are marked as "class powers"...those will be different for every class.
Where are you seeing that?
I may be mistaken, that's always a possibility.
But I suspect you saw that some of the powers were listed as "Passive Feature" and some were listed as "Class Action."
The "Class Action" just means that you have to activate the ability with an action, as opposed to the passive abilities.
Please point me to another source if you have one? In all the mix of information that's been coming out, it's possible I missed something. But again, this is what I currently think you're referring to.
