Legion will occasionally burn and get mobbed, but usually, they hang back fair distance away with the rest of my carriers, where it does not belong.
I use non-bombers on Legion, and I usually build it primarily for flagship use. (The fighters are mainly for anti-frigate and anti-destroyer, to seek-and-destroy the cowardly AI that will stall until their CR decays to zero.) Often, I (switch and) pilot a different ship and pass the Legion to AI. If I want bombers, I will grab Astral instead. Astral is much better with bombers than Legion. I get Legion mainly to use as an Onslaught-lite with fighters, which is get to the frontline to blow big stuff up with heavy weapons while fighters take out the fast cowards my Legion cannot catch.
