Love this game, but xrays are fucking stupid. No input complexity, little risk, easy to combo into, and way too much damage. What were they thinking? And I thought up downs were bad...
They don't actually seem very useful to me outside of potentially ending a game with unbreakable damage. Most anyone can get 35%+ off one bar of meter instead of 3. Losing your entire meter on an attack that is blockable is not "no risk" with how important combo breakers and meter burned moves are, and these things scale like hell if you combo into them.
