Occasionally, I use Heavy Autocannons on Enforcers because I run out of Arbalests after using them on everything else.
I use mostly Annihilators on Enforcers because I can buy them on the Open Market and AI uses them to block incoming enemy fire (probably by accident). Annihilators work well for brawling, until they run out which is not very long.
As for Drover, it could probably be built to brawl, but with its system and stats, why bother? Better to min-max its fighter capability (which is why someone uses a carrier). And do not get me started on the (entry-level carrier) Condor. With low OP, junk mounts and stats, if I want anything better than Talons, I need to sack weapons. (That was not a problem when Talons were 8 OP gods worth 0 OP in that first 0.8a release.) While Drover can use all of its OP to pump up stats and grab hullmods after fighters, Condor needs most of its OP just to get good fighters.
Not fond of Lasher. It is a SO machine gun boat. It seems too slow without SO. Prefer Centurion over Lasher for steady non-SO brawling.
