There's nothing wrong or unusual about adding displays to psionics. Just about every class has unique mechanics, so why not psionic classes?
"The Psion under this build"
AKA: The Psion proposed by using the Cranium Rat rules.
AKA: The Psion with No components and no displays
AKA: The one being talked about.
Sure, you can add displays to the psion class. Not disputing that, not even talking about that. Paul's point was that giving the Psion free, infinite subtle spell (which does not include displays) is a massive power boost. And I was responding to Sabathius about why that was different than the sorcerer having Subtle spell.

It's the same reason the adult red dragon (INT16) doesn't have one tactic when fighting a tough foe of flying by at high speed dragon breathing then exiting the area and waiting for it to recharge and then flying back in and dragon breathing the area over and over until the party is dead.
It's bad encounter design.
As is an impossible to detect monster just attacking the party and running away without giving them a chance to do anything in return.
The bad design has nothing to do with knowing someone cast a spell or not because of components rules.
I'm going to have to agree with @Ovinomancer here. Saying that the Dragon who fights smart is "bad encounter design" then you are setting a bad precedent.
Now, I'm not going to argue that it is a fun fight, it is blatantly unfair to the players, but then again, the monsters never have to play fair.
