You're telling us that the only way a small fleet can compete with a large fleet is to become a large fleet?
In tasks that are intentionally designed to encourage the formation of large fleets? Well, yeah; by design.
This entire system is designed to reward the formation of medium-sized fleets. You're asking that it be repurposed to do the exact opposite. Real fleets encourage longevity of play; solo fleets are just attempts to get free bank space. Ok, great; the system lets you form them. The fleet base projects are deliberately designed to encourage you to move beyond them.
Not everything added to the game has to be of equal benefit to every player.
