This is completely apples to oranges.
A filler combo isn't the same thing as pressing a single button 12 times.
A maintenance combo isn't the same thing as pressing a button ONCE every 30s.
War's gauge spender isn't comparable at all to the single button press of Misery. You can Misery once every 90s, vs the plethora of times a Warrior can fell cleave in that time frame.
My spider sense is telling me they're going to design Sage fairly well and all the SCH's who are fed up with fairy clunkiness (read: Most of them) are switching.
