Right now PDR is pretty useless against tyrants with enough brain cells to brace as it does no damage.
It’s a little extreme, to make a weapon entirely useless against tyrants.
I think it should still do damage to bracing tyrants, either low DOT or just the initial impact damage
People already consider PDR to be the most underwhelming weapon that Sci has and I feel like the no damage against bracing tyrants just makes that situation worse
