Controller users are at such a disadvantage without a dymanic and responsive aim assist (AA). It is needed so that fairness can be achieved and allow controller players (EVEN ON PC) to be able to compete. It's not fun when TTK is literally a second and missing 1 bullet usually means you lose. This is especially true for aerial combat manuvering and shooting. The magnitism and how it activates too is very important. Such as being able to keep on players and acquiring targets is key to a good AA. The degree of leniency also needs to match as well, as controller doesn't have access to a naturally more precise level of aim as K&M does. If there are complaints about worries of AA being "broken" or "cheesy cause mouse players can abuse it", I also highly suggest looking at what Apex Legends did to fix this back when they had this same issue.
