I've heard both extremes of it broken and dogshit, based on its unique mechanics.
You start a battle in Shield mode, where your attacks only deal 1 dmg and have a reduced energy charge rate. Once you use a charge move, you swap to Blade mode, where you remain until you either swap or use a shield.
There's apparently a "feature"/bug that makes it take way less damage than expected in Shield mode too.

It can't be used at all in PVE right now.
