Upgrades should always improve the ship! (Burst is a bit broken)

You're right, the cost of fully upgrading anything in the game is an arm and a leg. However, it's not impossible. I've fully upgraded a squad of bolter drones, however it caused a glitch where only 4 drones would spawn, so I never did this again. My point is that if someone does the grinding to accumulate enough upgrade points, they will end up with an op weapon. Then any idea of pvp in the future is already corrupted because of the ridiculous power provided by one weapon alone. Add 4 more weapons, and several drone squads and then what? It would just cause problems in my opinion, but my opinion very well could be flawed.
