So I really don't know what they were thinking with how they set up the favorites/presets. If you change to a different class it automatically favorites everything you had on. This in itself is not a terrible thing but then when you get updated gear there's no way to unfavorite the items, you have to be the same class as you were when they got added to favorite. Problem is now the class you just left has them as favorite too. So now you have to play some silly game of musical chairs with your classes to try to get these items out of favorite so you can dismantle them. There just needs to be a button in your regular gear menu, just like with dismantling where you can favorite and unfavorite an item. If such an option exists it's not clear as I don't see it.
Not exactly favoriting, more like locking items. The star only indicates that an item is equippped in some loadout. I would much prefer if there was an actual favorite function, where you could set what gear you want as favorites instead of having the stuff locked to a specific loadout. Being able to set stuff as junk for faster selling/dismantling would be really helpful as well. Kind of like how it is in Borderlands 3 currently.
It's really annoying
