The long range conflicts early in the war were mainly with twin and four engined types, the Beaufighter was introduced in Malta and the bay of Biscay to counter the Ju88 and Condor and protect Sunderlands. Not really dog fighting but it was important.The listing was focused on twin-engined fighters.
While the Ju88 wore many hats, it wasn't a "fighter" any more than the B-25J was.
It did perform well in the night-fighter role, but not in a daytime environment where types like the P-38, Whirlwind and even Beaufighter would be operating.
