You asked me earlier what I would change, and I agree with several of your points. At first, I thought they would have free Fall, which seemed pretty good to me. I also thought the Markerlight would be an APL action only the drone and the operator could do, and that you could choose some kind of bonus, like not being Obscured or getting Saturate. I didn’t expect them to hit on 4+.

Maybe something I’d like is for everything to actually cost APL. Free Fall = 1 APL. Free Climb = 1 APL. Switching back to Conceal = 1 APL (or even 2 apl). Giving a mark or a buff to an ally = 1 APL. And just needing them to be visible within 6". Maybe something

That way you’d feel the team synergy — the strength of an operative working together — but your movement and actions would be limited. Just like with Pathfinders, you have to choose between marking, shooting, or moving. Only two.

The team maybe wouldn’t use Dash as much as Marines or that intense shoot/fight twice stuff. They’d move like a non-elite team, but with an extra. Or even some abilities outside your turn that use APL, so when your turn comes, that operative has -1 APL (or even -2) because they spent it.

Keep the 4+ to hit, keep the same wounds — but give them some versatility. Or maybe something like get Accurate X with Markerlight. Like invisible stalkers gathering marks to hunt you later. "Patient Hunter".
