ESF engagement radar was added specifically to giv newbies a leg up in the airgame and show them how experienced pilots fly. Experienced pilots use stealth, entirely negating the function of engagement radar. Experienced pilots also use engagement radar to find and gank newbies, making it harder to learn the airgame instead of easier. The solution is simple: make engagement radar a defense slot item that all ESF start with. If you equip stealth you automatically lose the engagement radar. To further help newbies with engagement radar, if you receive damage from a source (ground or air) that source is automatically spotted, and aircraft that damage you will also be visible on the engagement radar as if they didnt have stealth whenever they are spotted.
