Using Void Tempest was a given. =p I know how it works. But yes, Tiger Blade has a ton of advantages over Crescent Strike. More hitstun, next to no recovery, it puts you into the air, it's easier to put the enemies into proper spacing for other setups, it has a better FOF change than Crescent Strike(Multi-hitting AOE that gives + frames on block? Hell yes), etc... Really, Crescent Strike is fine if you aren't trying to be super-technical and fancy like me.
