Please, kindly reconsider adding this. It's just a nuisance, and with the rng of drops, you can and will be potentially stuck at the same level for weeks on end because the game wouldn't give you a class item/boots or whatever the case may be. If it MUST return for some reason or another, please add in a way to either focus or have they game weigh in what you're still missing as a pity system.
Thanks for looking,
Cheers
