I think that I don't like or don't agree with the removal of 'margin of error' into the ability of Luftwaffe escorts to successfully accompany their bombers to the target. I hope that the final version doesn't remove this -> perhaps reducing this 'margin of error' would be the best thing to do, not to remove it.
I don't agree with this removal because this was realistic and IMO will make the sim more challenging as it is expected on such as sim!

BTW, does the removal of this feature also affects the RAF campaign? If yes, one more reason why I don't agree with this feature since it will make the RAF much more 'unrealistically' hard.

I wouldn't worry. I am also against changes that alter the play balance where it is not needed. You won't see an impact on the RAF campaign because to use escorts properly needs player intervention and the LW AI doesn't replicate this.

But the Luftwaffe campaign was very hard for players to even win, maybe too hard, especially when escorts almost NEVER joined up with bombers to target.

No, sorry, the multiplayer update will require a experienced multiplayer programmer who understands the details of multiplayer design and can tackle and understand the BOBII multiplayer as it is very old (1995 technology). I have got it working and we have played it many times but we have identified some problems that I just do not have the multi player experience to resolve.

These multiplayer skills are in demand and finding a volunteer is very difficult as a good multiplayer programmer can earn money in today's tight economy.
