Short answer: yes
Long answer: The more high value a set is to you, the more likely you should be to have less strict rules. For me personally, sets like Immunity and Stone Skin I'm more lenient with, whereas a more mediocre set I require near perfect rolls because I'm very, very unlikely to use it outside of a broken set.
I have 300+ gear overflow into maibox. It is all 5* and 6* epic and lego. I have to get strict with 5* and 6* rare to make room. I still need a few strict rules for myself and I learn the nuances of gear.
Thanks everyone.
