I've tried other gachas but this is really the only I've lasted more than a handful of months (I think Crestoria's my next best at like 4-5 months)
It always gets me when I try others and the number of dupes they want is just absurd, like Crestoria wants like 11 to finish a character + their memoria stone. Like yeah Omnia has many weapons per character but it's essentially one per era and it's not a hassle to max them from a single. The other weapons as well are really fed to you so it's not a concern, you just want to snag that FR & BT.
