The Brawler is a sad, sad ship. And it really bums me out because I wanted it to be sweet.
It's absolutely useless against most Frigates and Fighters because it's incredibly slow, has all hardpoint weapons, and has front-locked shields. All most Frigates need to do is hit it with Salamanders to cripple it's engines, then fly behind it and shoot it in the back. It's tremendously slow speed and wide, easy-to-hit shape makes this easy.
And if you try to use it in a "Gunship" role, taking on Destroyers and such head-on like it's Frontal Shields and Hardpoints seem to suggest...it gets DESTROYED. It simply doesn't have the firepower and armor to stand toe-to-toe with Destroyers. And it doesn't quite have the speed to out-maneuver them.
So you basically have a ship that's near-useless against Frigates, but still can't hold it's own against larger ships. It's pretty much a joke right now.
Ideally, I think they should boost it's speed by a lot. Make it able to at least keep pace with Frigates. Make it as fast as a Hyperion or something similar. It should be that ship that can blitz you head-on and get in your face with a lot of firepower. Make Brawlers feared ships that would have to be dealt with in their own way.
There's no other Frigate that almost exclusively front-locked shields AND firepower. Give it at least average speed, keep it's maneuverability, and up it's flux-dissipation by a little. The "High tech" ships have their shining stars, the Tempest and Hyperion. The "Low Tech" should have the Brawler as theirs. A ship with powerful frontal firepower and shields, but no rear defenses.
