Most DA ships have one or more crippling weakness, and using build strategies and builds to make the fleet work is quite fun. Although I do have a few suggestions towards balancing some problematic equipment.
Large slots on DA ships are very rare, and the ones that do exist are almost always rear-mounted on long ships with front-facing arcs. This naturally makes Uhlan Siege Laser a far better option on DA ships than other DA large weapons. The Monstro and the Opfer are ok on vanilla ships so I think this is mostly a ship problem. Maybe in the future, some ships could use them better. However, the Hexafire/Twin Hexafire are quite weak. I suggest giving them EMP effects similar to the small variant.
DA-only fleets are quite lacking in kinetic PD. Maybe it could also be added in wanzer/interceptor form.
Officer rosters that lead to success in DA fleets are often mostly or all aggressive and above. However, the beam wanzers are often used as extra PD, and aggressive officers send them out when they shouldn't. There should be a way to configure this specific wanzer's operating range to 1000 or below.
Assume wing control ability should give the active fighter some sort of buff such as a weak dampening field or extra repair speed while active.
Large missiles on the wishlist
Medium and large micro missile launchers also on the wishlist. With enough missiles mods, micro missiles can be accurate enough to be more than a distraction. But such options are usually limited to very few ships, most of which have built-in arrays.
