I guess im missing the point
The only classes that rely on psi is monks every class i play i barely use my psi except maybe the skill buffs . And this is on a melee tank (90% of the time i dont bother with basic resist or deflector) droner i never buff anything but a basic spy buff when im running to and from a place , my pe driver pistol never uses buffs (dont need em in a rhino) . Personally i think you are overreacting to psionics in the game . I hardly ever use a ppu to level and the only time i would really welcome one is in PVP which i dont do much as of yet .
