Just so you guys know, there's going to be a ton of added blocking animations in Beta 2, due out sometime within the week. This is most likely what you've been noticing that seems to be "wrong" with blocking. All the correct effects are still there, so it parries, block, and does knockaways when it should--it's just that some of the accompanying animations aren't showing. The non-attack damage blocks are most of what's missing, along with some other regular blocking animations. All of these will be in Beta 2.
