I think HT went to considerable trouble to TRY and keep it REAL ... Fuzed Ammo, Manual Ranging, etc ... RATHER than just adopt an arcade -Point And Shoot- system "for gaming purposes." I think further work is needed. The historical -BARAGE- technique can be modeled. A 3 or 4 gun battery with central OPTICAL aiming console IS REALISTIC and does allow visual targeting. I think adjusting range finding crosshairs might be a lot more intuitive than trying to chase numbers under an Icon and that players would find it MUCH more stimulating. The only shortcoming I see is that it adds objects to the ground clutter ... But not really that many.
If perk points and score are all that interest you, that's a good policy ... If you want to DEFEND your bases? chasing bombers AFTER they drop fails miserably. Base DEFENSE IS POSSIBLE, but it won't maximise your perks or score ... AND it requires that you accept risk and act without complete information about the enemy you must confront. The 88s were added to ENHANCE defense capabilities.

The idea I came up with for a 88mm flak targetting system doesn't sound easy at all. The player still has to calibrate and range the target to give the gun battery the appropriate lead and fuse length to reach the target. There's shell randomization in the game, so this isn't some sort of laser beam - there will still be error. If a target is 10.5 k-yards (direct line of sight) away when the gun is elevated to a 45 degree angle, then the target is about 22,300 feet above the gun position. If fired at a 90 degree angle straight up, the shell would take about 13.6 seconds to reach this height and explode. The flak 88's should be used for immediate base defense against high flying level bombers; it shouldn't be expected to be an effective defense against zippy little fighters on the deck (that's what the 37mm field guns are for). In game currently, firing a single flak 88 at 20k alt buffs is not effective just eyeballing the lead and fuse length. I think we need some sort of central targetting device to manually calibrate the lead and fuse length - I'm not proposing some sort of automatic computer guided aimbot. Since it took crews of several people to operate both the targetting system and flak battery connected to it, I proposed the targetting and gun fire control system to be integrated into one position for one player to operate "for gaming purposes" as there aren't any other vehicle in game that requires more than one person to operate.
You're either misreading my comments or completely misconstruing them. If you want to effectively defend a base against a set of buffs then you need to be already at 20k when they hit your base's DAR ring. If they have any sort of respectable altitude you're still not going to prevent them from dropping their ords on your base even if you immediately take off when they enter the DAR ring. For example, a b-17 as dictated by the AH speed charts travels at about 258 mph at an altitude of 10k-feet. The DAR ring has a radius of 12 miles. At this rate, the b-17 will cover the radius of the DAR ring in about 2:45 minutes (any higher, and its even faster than this). Are you saying that you can up a fighter (non-163 or 262) and be able to intercept a set of buffs at 10k or higher
before they drop on the base? If you don't, then you are not defending your base - you are attempting to catch the suckers that just bombed your base. The flak 88 should be used as a last line of defense against bombers within visual range of the base. If you first spot a buff 12k-yards away elevated to a 45 degree angle, they are at a ground distance of less than 5 miles away and will be directly over the top of you in little more than a minute. Assuming that you're waiting for them in the gun position, that still doesn't give you much time to calibrate, range and fire at the buffs with at least some sort of system. You're certainly not much of a threat now firing at 20k buffs completely eyeballing the lead and fuse length for the target in under a minute. In no way do I imagine this being a reasonable way to bring down fighters. They're going to be zipping around too much changing alt, course and speed to even try to calibrate, range and fire at. Furthermore, how did you even come to the conclusion that I don't like to up from a base that's already being attacked was because I don't like defending and was only concerned with perks? I don't up from a base that's already being attacked because I would not be defending the base, but playing catch-up to the buffs as they bomb more bases or try to RTB. I up from other bases to get ahead of the buffs and defend the healthy bases.
Edit: I talked to Vilkas. He said that the AA gunners used an optical instrument to range and calibrate the amount of lead and fuse setting for the projectile at the gun batteries, but since he was stationed on a 20mm gun he only heard that the flak 88 crews had radar (maybe later in the war).
