Of course impatience is the reason the animations are bad. It's great that you can enjoy the animations, but not everyone can, especially after the first run through the game, so the ability to TOGGLE them on or off is kind of essential. Forcing the player to wait, unable to do anything, for an extended period of time, is always bad design. The other FE games either do not have this problem at all or have it to a much lesser extent, so it stands out all the more for FE9.
