Ana's friendly aim assist

Friendly aim assist is really helpful on ana but it also isn’t at the same time due to how clunky it is when teammates are grouped. I wish they would rework how the friendly aim assist works to make it more accurate and/or add a friendly aim assist window size. I tend to fine anything over 80-85+% is just too clunky (example: I’m trying to heal my tank then my dps walks across my los and the aim assist will follow the dps rather than the tank im trying to heal).
