[dev1058] Why has animation-lock during movement/combat not been addressed?

[Celeras]

More likely it's not been addressed so far because it's not easy to solve at all. Enabling the players to move during an animation would likely require SE to remake most if not all of the animations. That is not feasible at this point in development, where they need to get the game to a playable (and billable) state ASAP.

If it wasn't easy to solve, FFXIV wouldn't be the only game in existence that forces it upon you. More likely, its a difficult thing to actually let slip through the alpha phase.
