I would support 4 bombers minimum required to take out a battleship, if I didn't know how hopeless it looks to try to fend yourselves in an all fighter force against 2-3 battleships at the same time. How many people do I have to call online to stand a fair chance? 8? 10? All in bombers? It's not a rare thing to get attacked by 2-3 BHG BCs when you're an unlawful, especially in New Berlin and as it is we need to bring a force of about 5 people (2-3 in bombers) to stand a chance against the indies in there, nevermind holding a position. It's fine the way it is with two-three light bombers being able to take out a no fighter escort battleship, and the heavy bombers need to have their agility upped to be able to do that as well.
Apart from that however, I still stand by my turn rate decrease for most bombers, the light ones especially. A turn rate decrease will make it easy for fighters to stay on their tails, and shoot up their behinds with cannons and possibly even razors. People just need to apply some tactics.
