The 110 doesn't compare to the Ju88.
It doesn't perform above the most common versions. The hp boost was minor and nearly insignficant. The Ju-88 we have carried thousands of pounds more bombs and had longer wings, 50% more defensive guns, and is over 20mph faster than the majority of bombers during the BoB. It turns what should be a "defend the bombers" setup to "the bombers will always get through, drop their load, and you will never catch them after the initial merge" -- not even slightly similar to a small limited number of 110s being used for BnZ.
EDIT: I wouldn't be opposed to some sort of restrictions on the 110C use such as dictating that it must be used for bomber escort or something like that, but then the same thing should be applied to the spitfires and hurricanes. They shouldn't take off until they had definitive contact and had to climb up to engage targets. As it stands the 100 octane update has made them mini-monsters when used unhistorically... you know... kind of like how the use of the 110c makes it more effective than how it was in the real BOB?
