I think it would be interesting and more strategic to have a rule to deploy the last asteroid (or debris) after all ships are deployed.
Alternatively, this rule can be edited like "Last asteroid has a level of "5", which is equal to pilot skill 5, so it gets deployed after all ships with PS under 5. Therefore, giving lower pilot skill pilots an additional disadvantage during game.
Example: All but 2 asteroids are deployed. You have to counter 4 TLT squad in the corner. With your last debris, you are trying to block at least one possible route to impede or hamper your opponents ships and give your ships for example better opportunity to circumvent firing arc. Or prevent/hindering efficient jousting etc
Any thoughts on this?
