If you are solo all the powers are still useful, like I said transference transfusion, speed boost, and even repel are all very situationally useful powers.
The meat and taters of the set is fulcrum shift, but just because it is doesn't mean the set as a whole is indicted. That's mainly an indictment on incarnate abilities, and set bonuses - no I'm not looking for a nerf there but top tier builds don't need heals or endurance usually.
Fulcrum shift is the payoff punch for kinetics on incarnate teams and that's more than fine.
Wording about the lesser powers is like an incarnate tank worrying about their T1 not doing enough damage. It's still there but I'm popping lightning rod, ko blow, crushing uppercut, footstomp, etc as much as I possibly can.
