Even in the PNP, it's a trap. You get higher AC running Dex and grabbing some Monk levels, grab the same feats, now you can blast with or without the blade.Well, doesn't mean a Kinetic Knight's useless. Actually his playstyle might be less rotten = more fun then Deadly Earth spam of regular Kins.
The whole point of Kineticist melee is the Kinetic Whip. Without the Kinetic Whip you can't make AoOs. Not to mention full-round attacking with that reach + tripping + disarming weapon.
