The whole GAS unlock event is a rage inducing RNG fest. Honestly don't know what value is added to the game by making it so difficult. Maybe when he was first added to the game, I can see this being a way to reward people who are particularly persistent, but at this point in the game even though he's still a really good character, they should probably ratchet back the RNG shenanagins. Even after you unlock him you still have to spend tons of GET1 over weeks or months to get him to 7* - to me that feels like enough of a gate to justify an easier unlock event.
Suuuuper frustrating. I didn't even put gear on him for weeks after completing the event because I was so disgusted with the whole thing.
Unreasonably difficult. Massive inconvenience.
