Couldn't agree more, and just to make sure this comment is more downvoted than the OP, i'll take it a step further. It should have CoDs radar. Mostly that you shouldn't show up as a red dot until you've fired your weapon, or used a super/ability. An overly detailed radar unfortunately does the same thing no radar does and makes so many people scared to move their feet. Retuning it to function more like other games would absolutely help address this.

If everyone knows where everyone is then everyone has the same information and we're all on equal terms...what exactly is the issue?

Nah. The radar should stay the way its always been. How would that possibly help new players? Its also less info for the individual player period in a game with a constantly shifting meta that does and always will include ridiculous stuff that we never could have dreamed of in D1. D1 was so much more like Halo than Destiny 2 at this point in terms of gameplay.
