The window for morphing and feinting is far smaller than warband (relative to the overall attack time), and being able to reset a released attack by hitting the ground (which isn't even doable for shorter weapons) is not exactly ideal control or intuitive, considering that there is a turnspeed lock (making it harder to suddenly drag an attack into the floor) and there is still a "reset" time from hits that connect with an obstacle. Warband is far simpler: for 95% of the time you are winding up or releasing, you can cancel or block during that time, and most weapons can be made to hit instantly or later. I don't think it's arguable that Warband is less complex and gives more control to the player.
