Wouldn't the 110's get mauled if they were just hanging around England looking for a fight? I think they would only be effective at surprising aircraft taking off or landing, or hitting bombers. I imagine almost all Allied fighters would run circles around them in a dogfight. So, they couldn't really hang around waiting too long or allied fighters would come along. I'm not an air guy but I don't think the 110's were overpowering any Allied fighters iirc. (Correct me if I am wrong.) Did the Germans do this in the war? How could it be a game changer here?
I used them a lot to hit fighters on the ground in the original game.
It was the single best mission for 110Ds, for example.
Their endurance, sturdiness and firepower are way superior to 109s. Plus you can assign 109s on a higher altitude in a FS for cover.
The historical performance of the 110 wasn't so terribly bad as people today talk about it.
It was inefficient - you could get two 109s for one 110. That was the problem.
The average 110 pilot was better than the average 109 pilot, for many of the better ones were sent to the ZG.
110s could not be surprised (surprise = main killer in fighter-on-fighter combat), but in exchange they depended a lot on team support to survive (for they lacked defensive manoeuvrability).
Their offensive strength was fine. They were easier to see and thus a bit less likely to surprise the enemy, but their firepower was great and concentrated, their speed was good and they were steady gun platforms (easy aiming on a surprised0steady target).
In case of troubles they could fly in a circle. It wasn't until 1941/42 that fighter pilots in Europe figured out how to defeat a defensive ring of fighters (see Joachim Marseille), and the tactic against such a circle formation required great pilot skill.
