I have a general preference for positioning over coordination. I’d rather have an efficient exchange (I get many/good shots, my opponent gets few/poor shots) even if I’m not concentrating my fire. I’m often happy to change targets and let a wounded ship run away for a while if it means I get a better exchange with the remaining ships.
Obviously finishing off ships is more valuable than spreading damage around, and I’ll go for that opportunity if I think I can set it up. But if I have a risky option to set up an enemy ship in a killbox vs a reliable option to keep my ships safe and get some damage in, I’ll usually go for the latter.
Even if it’s not my top priority, though, the threat of concentrated fire is still an important tool for positioning. If I’m scattered all over and my opponent can focus on offense without fear for their own ships, I’m probably not setting myself up for good exchanges.
