Animation Lock: Why don't you like it?

[Zantetsuken]

They also allowed the player to dodge, breaking the animation you were locked in. (At least you could in Monster Hunter, I don't remember much about Demon's Souls/Dark Souls.)

True, and that is what is needed in this game -- a window for breaking/cancelling your attacks and spells.

But allowing players to run around full-tilt while executing Chaos Thrust, any other multi-hit WS would look ridiculous - with or without animation blending.
