Normally i would agree with this idea,
But Enix ...
I would be very displeased to see this name lost.
It would be dishonorable and disrespectful.
it is ENIX.

Maybe go take a look at the list of games Enix made before Square swallowed em up eh?>
It would be an even tilt to say that Enix should just drop Square and rebrand as Enix.
Square Enix is fine.
