The TB Brawler explodes if any torpedo or ship blows up near it. Is it meant to be that fragile as a Brawler, a knife fight ship? With one of it's guns missing and it's shield taken away for a shield/armour plate, you would expect it to be at least decently durable or speedy to be able to do what it is named after, brawl, but you can't get in close because ship explosions will kill you, and you can't escort because eating a torpedo means death. Just giving it's shield back would do wonders for it, having the armor plate be a sort of backup shield and armor to soak up normal bullets but not be able to stand explosions.
