I don't really have a problem with them being power weapons. DCA will smash anything they hit, and then evaporate, and that's that, pretty much. It is a little funny that the sister's DCAs are a little nerfed for no reason, but you're almost sure to use Inq with your sisters now, anyway (which is good, that's as it should be).
But, illustrative as how bad this all is...they've changed new psy-shock entries to be "unsaved wound" which as discussed, is worthless, but in line with previous GK FAQ. OK, but new psy-shock also affects psychic pilot vehicles......who cannot suffer an unsaved wound. WTF?!?
BTW, the Inq Orbital strike follows the "unsaved wound" rule too, which is the opposite of how the GK blasts work....so fail again. WHy can we have no consistency? This reminds me of the old bull-crap where the assault cannons from some codexes had 3 shots, others 4 and rending.
