This statistic is easy to diss when you see noobs that keep upping bombers from a capped field, to the grand pleasure of jet dweebs. A regular pilot will loose a bomber formation every 20-30mins, some noobs it's every minute without firing a single shot.
A decent bomber pilot will smoke your engine (or worst) 800 out whatever your angle of attack is. Fact is that a bomber formation entering radar at 15K max speed is nearly unstoppable (actually it goes faster than a lot of mid war planes)
The situation in aces high is like in the early 20's, when fighters were regarded as obsolete due to the cheer speed of bombers.
It goes both ways: Noobs that keep upping in buffs from capped fields as well as noobs attacking bombers from plain 6.
If a decent bomber pilot will smoke you 800 out whatever your angel of attack is, I got good news again: We only have very few of that kind. Guys like triple 9 are incredibly rare. The utter majority of buffs I encounter at alt are simply dead meat if they don't get attacked from their plain six - which IS the prevailing mode of attack.
And yes, a bomber formation at 15k entering dar is nearly unstoppable... if you are still on the ground.
I see no problem with that, because it's easy to read darbars, fly patrols and so on. It's easy to stop them. You can even kill that bomber before he comes around for the next hangars, if you take off when he enters the dar for the first time. A BF 109K takes only 4 minutes to get to 15k.
With the notable exception of the B-29, bombers are meat on the table.
