You don't need a fleet of 30+ fully G5 engineered ships. Again, this is something you have chosen to do yourself. Nowhere in the game does it say you need 30+ fully engineered ships.Try to build a fleet of 30+ fully G5 engineered ships for various roles and tell me how you will manage that without grinding. There are a lot of materials involved that must be farmed, as just running across them in large enough quantities is just not happening. My fun begins after I've acquired all my G5 precision tools and get to use them.
You've only got yourself to blame for that one am afraid. As I said, the only grind is the grind you bring with you. If you can only find fun when you have the best of the best, then that's an issue with you, not the game.
