*raises his hand, too*
Thunder & water still got one wep remaining.. and I'm playing for almost a year actively.
Anyway, some ppl keep picking up a topic MagicSpice explained beforehand & it is reasonable. Not much around it if you don't have enough time.
That said, not getting any whatsoever assault wep from disasters "for months" seems ridiculously impossible, especially with rag raids only dropping that very assault weapon. If you join a few a day, you're bound to get some. I used to farm disasters, too & while it's true there might be some empty streaks, but the highest I reached was 9 days without assault drop, and that was for one specific element (unsurprisingly, that element was light). Plus there were no rags back then.
Yes, Atlante's best trait is having C-12% (AoE) def debuff, which proves really handy for those without Cthulhu. Other than that, she also has guaranteed DA & invic + 50% elemental selfbuff.
Cool free SR himes, banzai!
