This. Body blocking is great in theory, but I've yet to see it implemented in a way that didn't feel excessively intrusive. For example, in GW1 the body blocking coding causes a lot of rubber banding issues of the game thinking you passed the block, then realizing you didn't and throwing you back. It's one of my biggest gripes with the game, even though I love it.
Plus, it always seems to be overdone. I'd be fine if the block was a 1 or 2 ft space you couldn't enter, but in most games the block feels like 10 feet wide and extends past the physical appearance of the target.
