It's a bit weird to me, I could see a talent letting you copy the effects of your opponents rage, but not protecting you from the rage of others. Thya adepts could possibly have a talent that let them calm others, ending rage prematurely.
It's not a bad idea to start with, I just don't agree with the effect. But I guess it would depend on the tradition using the talent and the fluff description. If it is some form of premonition, tapping into your inner calm to anticipate the moves of the enraged opponent, then maybe. Should require the expenditure of an instance of Farseeing if that is the case, maybe a swift action to maintain the effect?
