Well, cherry picking is alread ya real thing, so I wouldn't worry about it too much. As long as an ability does not harmonize with too many other things to make them all OP it should be fine. After all, even Action Surge gets a pass, despite being a massive power boost.
As far as I can see, the classes Solidify at 2, where you generally get the mechanic that sets your class apart from the others in the book. Then at 3rd you get the abilities that set you apart from the others in your class. I personally consider this Identity to be more important than cherry picking possibilities, as it is what makes a class interesting. IMX, the 3rd level is the point where someone decides "I want to play that class.", and that is an important thing to have.
