The animations right now look very choppy and somewhat slow, caused by the block-hitting setting of the mod. This changes how a lot of the items behave, causing their swings to be delayed (upon left and right clicking items, such as a potion or a bow clearly shows the issue).
Having this fixed could really improve the PvP experience on 1.8 based servers and make pvping much more smooth. Right now it feels quite choppy and awkward to PvP with these current choppy animations.
A video is provided to show these choppy animations in relation to their 1.7 counterpart.
