I get where you're going with this - and full disclosure, I'm a big fan of 'the trinity' in gameplay design. That said, it's important to remember what Elite is and is not:
Elite: Dangerous is principally a
Space Flight Simulator
All of its features, from Power Play to Thargoids, missions to mining, are designed with the simulator - the piloting of a starship and using its capabilities - at the center. This is why building wing gameplay mechanics or Squadron mechanics can be tricky: creating a Squadron UI for the purposes of communication and team building
has nothing to do with flying a spaceship. Yet if we get hung up on that fact, we'd not have much of a multiplayer game.
Relative to 'the trinity', building that into a flight simulator is doable but requires great care in balancing. Suppose this feature is implemented:
- We can now refuel, rearm, and almost entirely repair a fellow ship in distress or need
- For the most part, we can do this for ourselves, too (refuel requiring preparation or a fuel scoop - a true 'distress' scenario and you're SoL)
Traditionally, Elite has been built with solo commanders in mind
first - Elite: Dangerous is a departure from that model. One of the greatest hurdles for Frontier as they develop this game is keeping that crowd in mind. Fleet Carriers make no sense to a solo commander and would, at best, represent an ornamental achievement. The same goes for squadrons and multi-crew, as well as the supporting limpet controllers. It doesn't make any logical sense, but I still wonder if Repair Limpets shouldn't be usable on yourself for the sake of building up that support role in a multiplayer game.
I don't want to see Elite move in a direction where the 'trinity' is necessary to complete certain aspects of gameplay, but it bears mentioning we have technically already paved the road there: Thargoid Interceptors are not balanced for solo commanders. Can they be solo'd? Of course, with great care and skill. But they are principally designed with
multiplayer in mind - team work. Same goes for the support limpets, SLFs, and other multi-crew designated features. Can you use ECM as a solo commander? Yes, absolutely - but a gunner can use it much more effectively as they can focus on defense while you focus on piloting.
So I say all that to say this: I think the trinity has a place in Elite, but that place is
very minor and serves more as a tactical option for team building rather than a tactical
necessity for goal completion. Until we see major features implemented (like fleet carriers or squadron wars or what have you) that are multiplayer oriented, it's hard to say what the future of this iteration of Elite looks like
beyond the flight sim. Until then, every feature I propose (or provide discourse on) is viewed from the lens of 'how does this benefit the flight simulator'...because that's what Elite is.
