On Puck's observation of killing one B-17 and getting the second free: What happens is when the first bomber dies, the second bomber jumps forward into the same space filled by the first bomber and starts taking hits. You don't have to adjust you aim to hit the second bomber if you get an instant kill (explosion) on the first bomber. You may be able to get all three bombers this way.
I agree with Puck that we need targets worthy of bombing. Don't want to see them decrease the effectiveness of the JABO or perk bombs or make targets harder to make the bomber more important - just make more targets. Currently, a single, fully loaded, P-47 has more than enough firepower to knock a town down. Instead of robbing the 47 of its ability to (or fun in) destroy a building, just make the towns with more buildings then a single P-47 can destroy. Apparently, according to muckmaw, HTC is in the process of doing this with field towns. I would also like to see this done with the fields. For example, have 3 FH clustered together in a group and have several widely spaced groups on a field. Now, if this causes a big hit in frame rate like Wotan suggests, go ahead and make the targets harder; but also make them bigger so we can get more bombs on them with the delay set at 0.05 - would like to be able to destroy a harden target with a single pass of the bomber. (I don't even want to get started here on salvo vs. ripple modes of bombing.)
It is interesting to note that these same discussions over Bomber vs. JABO have been going on since the airplane was first conceived as a weapon. What would the outcome of WWII have been if, instead of a thousand plane bomber raid on a strategic target, there where 10 thousand JABOs? The outcome would not have been as good as the fighter advocates might think. The aspect of the bomber that was important in WWII was its range. Fighters couldn't even reach the strategic targets. So even if a whole group of bombers could only manage to get a single 500 ponder on the target, it was 500 lbs more than the entire fighter force could do. Unfortunately, or fortunately depending on your point of view, range is not a factor in AH and thus negating an import aspect of the bomber. The only thing that is important in AH is the ability to inflect damage. As muckmaw pointed out in his list of bomber problems, that advantage to do that damage currently goes to the JABOs.
