I disagree. Strongly. Bomber swarms still cause a lot of pain. The effectiveness of Nova's still rise exponentially when in groups.
Ask those lone LNS-ships getting picked off by single bombers in Bering/Hudson if bombers are still effective. I killed a LABC there alone in my bomber the other day, and the noob LABC captain actually sent a // message saying Nova's = cheating and that I "have no heart" for going up against a cap in a bomber... I guess "cheating" is all a matter of perspective.
It is a rather common occurence to see LNS-tagged ships getting pirated by 2-3 bombers, even in core systems such as California.
In fact, shooting capital ships in Liberty is sort of a local sport for pirates in bombers. Everybody rejoice when they spot an un-escorted LNS-ship.
Only problem I really see are the gunboats. Reduce agility on those, so they are easier to SNAC, and I will be all happy.
I think this debate has been totally de-railed by scenarios of doom and other "what if" situations, rather than actual in-game experiences.
