The problem is that bjj has to be 100% usable in its practiced form. A fake or pretend strike is going to have 0 effect because we know you can't strike in grappling competition. If you want to learn strikes in grappling, then use strikes. The whole fake striking thing always irks me. I can plainly see the person is not going to hit me, so why bother defending. I know he wants a response to use against me, so I will not give him one. But if he hits me in the face, he gets a response no matter what.
Right -- I was thinking maybe some sort of nuisance maneuver like pushing the neck or jaw. But anyway, it was just an idea; I think it was probably not a good one.
It's sort of sad how happy it would make me to be able to pull off aikido waza somewhat reliably in free grappling. There are definitely times when I wish I'd never done aikido, because now I like the art too much to just drop it, as bizarre as that might sound. In the meantime, I guess the best thing to do is keep working at it.
