are 110's restricted to bomber duty only?

I may have said before but being out run and out gunned by them in previous scenarios it makes me want to puke.
Then they have the cheek to level off and start using their rear gunner on auto pilot, like I was not mad before, that my Beautiful awesome Spitfire couldn't catch you.
I must have missed something in my pro British textbooks on how awesome the 110 was in A2A combat against single engine fighters.
