I've been playing in an online game for the last few months as the "telepath" variant.
It's a frighteningly powerful social class, and you can sometimes use the "belives one thing to be true" power to devistating effect. In combat, however ... Outside of taking the high PP risk of puppeting an opponent for a round, it largely plays one-note. Sort of like the Warlock eldarich blasting everyone, except I don't even get the joy of to-hit rolls.
I would be unsurprised to see the Object-Reading power nerfed, or moved into a domain. It's potent in an intrigue-style game, and it's the sort of thing that you should at least have to pay for, I think.
That said, I do really like the domain setup and the psionic focus mechanic, and I love the mind vault disicpline. I also suspect that taking that displine, and forgoing some of the more combat poentent disciplines is why my bullet-time feels so monotonous -- it's more in the build...
So, generally -- I really like the take on the class, and it definatly feels different than playing any other class, which is important. Some tweaking and balancing is still needed, but overall:
