Some decent points, but I think you're also too critical. The game doesn't need a complete overhaul. CQC, Powerplay, Multicrew don't require overhauls. The foundation is decent, they just need to integrate it better into the main game and give it more variety and depth in terms of gameplay.
CQC needs bots to fill matches and option to wait for a match while in the main game. Powerplay needs to be more player driven and player controlled. The player factions in Powerplay should be player managed guilds imo, that would add so much depth. Now player actions in Powerplay are superficial, because we're tiny gears with little agency. Multicrew needs more PVE gameplay and should be more like Star Trek: Bridge Crew and add NPC crew.
About PP, guilds wont help when people will grind in SOLO or press the block button when they see a hollow squere. No point in changing features when the fundamental design is broken which cant allow the content to exist to begin with.
