3GA and 4GA aren’t really needed anyway unless you are pushing high level pits and by that point you are 1 tapping everything out there that doesn’t have forced immunity phases.
I play completely solo and have no troubles getting what is needed without grouping or trading. Some meta items can prove difficult is that they changed up target farming to all the lesser bosses. What they need to do is revert the changes to those drops and eliminate the general pool all together because it waters down the drops to the items you are targeting.
