As an unapologetic alt monkey, I love to hunt bombers. I possess the one thing you must have to be successful, patience. Everything else you need is a skill that you will develop, IF, you have patience.
I don't think anything needs tweaking or changing. If buffs are below 20k, they are dead quick, if they are higher they are dead too, it just takes a bit longer.
Yes, the buffs have a very stable gun platform to shoot but so do the fighters, no turbulence, no jammed guns, no dud ammo.
If and when, you develop the skills and have the patience for a quality intercept I don't think anyone will want it easier either. I want this game to be hard, but with balanced gameplay and I think we have that now.
This month I have killed:
26 B17's
19 B24's
5 B26's
1 B29
36 Lancs
That's 87 kills and ZERO deaths and I am at best a mediocre stick.
A successful base defense means that I am killing guys and having fun doing it, could really care less if the base is captured during the ensuing melee. I know I can't kill them all so I never get frustrated or impatient.
