The real problem with these weapon’s and their potential is how absurdly long it takes to even get just 1 ultimate booster. The time it requires doesn't justify being a little bit stronger than the Dim weapons. Except for Rykross and Jupiter. The former being 3000% megids and already heavily used for synchro, and the latter actually buffing the lightning strike to 350% on top of the 20% pot. (Also seen as on par with lightstream during PBF, weaker when using kestral, and stronger when not in PBF)

1 booster in 8 hours, count me out.
