I land even if I do not get any kills, for instance, if I go on a buff hunting sortie, and do not come accross any buffs and run low on fuel, I go home and land. I land with no kills, with one kill, two kills and so on...If I get damaged, I always try and get back to a base and land. If its because the system messages spam your text bar, squelch them. But there is nothing wrong with the current system imho. The only thing I do not do, is re arm, I just get a new ship.
