Since we're basically squeaking about a preceding project and trying to extrapolate that into something we haven't seen yet, I'll throw in my $.02 on buffing in said preceding project.
Yes, it isn't very realistic, and no, I don't think it can be a perfect simulation of level bombing giving the gameplay limitations we have.
It's not just formation flying that makes driving the heavies difficult.
And, no, it isn't as simple as "pick your target, green up, open bays and pickle."
Plenty of part-time or vacation buffers may think it is, but it isn't.
First, of all, the WB targets have been hardened in a way that pinpoint precision is necessary if level bombing is to have any effect. If you screw up the split-second lead necessary on the pickle, you'll end up putting a huge crater underneath the target which IRL woulda been destroyed.
Further, the rebuild clocks require either a significant number of bombers, or someone really good. By really good I mean somebody who is capable of closing (or deacking) a small field in one pass, and a mid field in two. Take a look at the field layout sometime: to do that in a single level bomber requires the pilot to know instinctively the flight characteristics of the a/c, and to be able to exploit these while staring down the "Nerden" bombsight.
WB-style level bombing is certainly ahistorical and way too precise, but it is an error to maintain that it's easy, or that it fosters more "game" skills than "pilot" skills. As a solution I find it quite elegant: those meatheads who just want to hop in a buff and bomb something can get mediocre results, while those who really learn the envelope are able to achieve a legendary outcome.
The argument that Otto's accuracy is superior to the average fighter pilot's accuracy is invalid: maneuvering a plane and firing at a hard-banking spitfire is considerable more difficult that sitting in the back of a relatively stable platform (most buffs I shoot down don't squirt around much), and plugging away at a spitfire climbing at near stall speed. If you want to compare Otto and human accuracy, the only way to do this is compare otto's numbers against human gunners' numbers.
That being said, I look forward to seeing what HTC has to offer. Sure, cut the accuracy, increase the number and variety of aspects to be mastered -- I'm all for that. And I have the confidence they won't make some aspects of level bombing so realistic that nobody bothers to do it.
