This won't be fixed! Therefore I put the next question at hand.

Why design content to rely so heavily on this? There are plenty of mechanically fun fights that are nearly unaffected by this...

Garuda and Cadeuceus come to mind.

You give us a bazillion things to dodge and a system that doesn't perform well in that situation, we're going to complain... Since the system can't be changed, let's be honest, we'd prefer content that performs well within the system.
Simple answer: Left hand doesn't know what right hand is doing, SE tends to be a little more idiot that it doesn't even remember which is left and which is right.
Complex answer: It can be fix, they don't have the brain power to do it easily, and the decision falls into limbo.
