It's more about the grab animation that makes it jarring. I'd LOVE to see Dark Souls 3 completely do away with grabs, backstabs, and ripostes. Getting locked into animations, or locking your enemies into animations is always off-putting to me, and I know I'm not alone in that.
All I can think of are the Dark Souls 2 giant trolls, and how they swipe the air, then you get teleported into their hands for a snack.
