I've heard Arnk say that too, but I don't get it at all. You'd get more experimentation, more decisions, and therefore more configurations. People would equip their ships for whatever they felt like doing at the time (thorring, running, tanking, etc.), which leads to counters. I would argue that the current expensive item sale costs tend to drive everyone to the same generic optimally-balanced configs. E.g. every warbird last round had either a sig gun or a sig sublight, and pretty much the same everything else. It also favors rich players, who are less pained about the financial losses from selling items, over casual ones. I'd like to see more wacky experiments, like lancs with omega, tokamak sharks, etc. that you never see anymore because of this emphasis on making decisions irreversible due to the costs. The latter adds -10 fun and paradoxically drives everyone to the same optimal configs.
