I've had an annoying delay issue occasionally when doing AK runs. When fighting the Demon Wall, once in a while he'll do his Repel, and then nothing happens so I'll assume I wasn't repelled (which can happen once in a while with my pld). Then about 2 seconds later as I'm starting to move to avoid the floor gunk, I'll be completely flung off the platform. The annoying thing is that right after the Repel I will see everyone else being flung backwards, which is what makes me think I was unaffected by the blast.
