Why wouldn't it look like elite?
One of the few consistent things about the Elite series to date is that any ship can basically do any task.
Elite (1): you just had the Cobra III, so it was of course very good at combat and trading or you wouldn't have been able to play the game.
FE2/FFE: the purely volume-based outfitting model meant that a Panther was basically just a big Eagle with more shields, bigger guns, more cargo, and less agility.
Elite Dangerous: trying to exploring in a Gunship or fighting in a T-7 is a little more difficult but (especially with engineering, etc.) still fairly practical. While the outfitting is a bit more complicated, every medium and large ship is still basically a big Sidewinder with more guns and less agility.
In terms of DPS the Anaconda has only 8 times the firepower of the Sidewinder (and relative to its weapons' power requirements, actually a worse distributor) and - without piling on stacked engineered defence - only about ten times the resilience (plus the extra hull hardness, but that won't matter if the Sidewinders use railguns). That doesn't make the challenges they can face qualitatively different - sure, the Anaconda will go a bit faster and need less skill to keep alive, but pretty much anything combat-wise an average player can do in an Anaconda a really good player can do in a Sidewinder (there's video proof of this). The Anaconda costs 1000x the Sidewinder, though.
So the average player goes to face a task that needs an Anaconda and has medium risk. If they win, decent payout. If they lose, serious cost.
The really good player does the same thing in a Sidewinder with about the same risk level. If they win, incredible payout by the standards of what most Sidewinder pilots are earning. If they lose, virtually cost-free.
Throw in multiplayer and a wing of 4 decent Sidewinder pilots can probably do the same with only medium risk. Even split 4 ways the payout is still huge.
You can't make any sensible balancing of risk, income, costs, etc. in that sort of environment.
To stop that the ship tiers need to be made both qualitatively different and more significantly quantitatively different - an Anaconda not just a big Sidewinder. That's never been done in Elite (witness the culture shock recently from a Fleet Carrier not just being a
really big Sidewinder) and would require substantial rethinks of ship design, outfitting, and everything else ... and at that point, is it really still a Cobra III? Make a clean break on ship design and a lot of this gets easier.
The point would be that they want to produce a game that more closely matches their vision
If after six years of releases they've managed to make a game
this far from their vision I think there's only two possibilities.
1) You've misunderstood what their vision is.
2) They're so incompetent at going from vision to design to implementation that the odds their second attempt goes any better is probably not good.
I'm not saying your vision for a space MMO is unappealing - I'd probably give it a go if someone made one - but Elite V isn't going to be it.
