I'm not debating the fighting skills of the 88. I can't get the hang of it, but I know some people who can. Like yourself.
For the HE 111, as you said, it was a bomber. Not a divebomber/ attack plane like the 88. However with fighter cover, it will be able to make it to target and back. It is about team work. I'm also mad enough to try it un escorted as I did with the 87. Just because it requires a bit of extra work, does not mean that one of the most committed planes in WW2 should be excluded from the game. Heck, I have a BoB patch from a scenario and it has a HE 111 on it! A game patch has a plane not in the game because that plane is so Iconic!
