If you’ve watched the Beta videos you’ll have spotted that when mobs are taken down they can fly all over the place. When launched into the air they sometimes float down and slide. This is of course the physics engine at work, and according to Blizzard, what we see now is by no means final. As testing progresses changes are going to be made, although we may not know exactly when it happens as Blizzard states any changes are unlikely to be documented in patch notes. Keep your eyes peeled for changes as the patches progress.
I don’t want anyone to get the impression that we’re shooting for realism here though, because our goal is absolutely to make it feel like you’re an over-the-top human god laying waste to the demonic masses and setting their carcasses flying free like so much loosed meat. Also it is absolutely intentional that the barbarian’s skills have crazier impact physics than other classes, because we think that fits with the visual and feel of the character – huge impactful strikes that send dudes flying, whereas the monk might be more of a ‘thousand cuts’ kind of fighter.
There are some just straight up issues though we do intend to correct.
