For now on PS4, not sure how it is on other platforms, it is hard to track teammates.
*Add indicator arrow on inventory-map to show where teammates are in relation to where you are zoomed in
*Add indicator arrow on mini-map to show where teammates are
*Add indicator arrow in first person view on peripheral vision to show where teammate is (like BL2)
*To arrow, add red strobe to show when teammate is in FFYL (wife and I getting into arguments over this because we didn’t see them, do not need divorces over this lol)
*Make text bigger on arrow of their name. It is SOOOOOOOO small.
*Make text more legible in general
(we also found out the hard way you have to use fast travel to travel to teammates car)
Just want to say I completely agree. My partner and I are having issues playing because of the lack of tracking features in this edition of Borderlands. This is a huge issue that needs to be addressed asap - this failing in User Interface severely diminishes the User Experience of cooperative play.
