1) Hype.I kinda support this. On this note, can somebody explain why super moves are so badly telegraphed in a lot of fighting games? And ofc I don't understand why it applies to IGAU. I don't think X-Rays were issue in MK9...
2) They're powerful.
3) X-Rays weren't an issue because nobody did them due to 2/3 bars being vital for breakers. In IGAU you get 1 combo breaker per match each which costs 1 bar (out of 4) and some characters can happy sit on a full meter while still doing good damage.
4) Mainly hype. HERE COMES THE SUPER MOVE.
