@SaviorZero82 to add to what you just said, even after the 400% expired, my drops did not return to normal until I logged out and exited the game.
Clearly it's not just bad luck, but some malicious force infecting your 400% tickets and cursing you forever.
Ok then how often do you get photon boosters in AQs
Which AQ difficulty? Because if you were doing SH, I've never had a photon booster drop there, personally. If you were running a 400% on VH, that would be questionable, but not getting any boosters at all would be odd certainly. But just look at the posts here, on one hand you people are complaining about the items somehow being so bugged they break your drops forever - to one guy casually mentioning having "full sets" of saiki units and wanting more.
If they weren't working, you wouldn't have those multiple sets, dawg. It's not some great conspiracy, you're looking to blame your bad luck and buyer's remorse on the game because RNG did what RNG does.
