The front skirts severely restrict the movement of the legs. Usually not a big issue but the Exia was supposed to have human-like range of movement in the lore so.

The new Avalanche RG doesn't fix that either. There's also a third party add on that turns the base RG Exia into the Avalanche variant. Pic related. It comes with the Anti-Ship Sword that the Bandai version lacks for some reason.
