Honestly hasn't been much of an issue. All the atk down debuffs usually reduce the huge amount of damage you would take anyways.
it's not (if there's 6 or less and you got full HP), but it's a bit unnerving when you see the boss with 8-12 debuffs and she's about to use her move....
BTW, just got the SSR weapon in around 200 tickets total (i'm late playing cause work lol)
