I do believe skill button consolidation should only be done where it makes good sense to (why are the tank and dps stances still separate skills?!?) instead of trying to consolidate everything with even vaguely related skill chains.
That said, dragoon having eight buttons dedicated to basic gcd rotational skills seems a liiiiiittle unnecessary.

Paladin especially would benefit from merging skill effects.
I can't even fit all their skills on my controller without having to change crossbars in combat.
Seriously? 32 buttons isn't enough?
