I find the only units worth focus firing with are long range units and strike craft. Everything else does just fine if left to its own devices, and you're better off micro-managing cruiser special abilities. Strike craft have a nasty habit of, say, focus firing a Kol with adaptive shields on. BAAAAD idea, especially when there's a fragile Hoshiko sitting next to it. Fighters tend to prioritize other fighters, which is what you want them to do, but once those are neutralized sending them against smaller frigates is the best use of their talents.
