My issue with this idea would be for things like sieges, if fighters and bombers keep coming back over and over again that would be extremely tedious. I do think contested zones were cool and wish they could make a return but I honestly think the game is doing fine right now in systems like Theta without having people coming back more quickly. I do think it would be cool though to have some more respawn events though, the one in Omicron Nu between corsairs/order/outcasts/core/liberty/nomads was very fun.
