thanks Stream, I was debating this with DM and other players pre-play. I was saying they can be tripped, knocked down eg feats work as intended. My opinion was chalked up as bias, I was making a 10th level Monk. BUT I could not grapple or hold him. Then they started to debate bull rushing VS FoM.
The rules seem soooo ambiguous, its almost laughable, almost, mostly irritating, but still just shy of a chuckle!
