On twitter they said:
"As for the unit, we have a common unit that is similar to Legions, so we wanted to make the Roman emblematic unit different."
Common Unit I can sorta accept - Mithradates of Pontus actually tried to form his own Legions against Rome - armored swordsmen with big shields - but the Romans stomped them anyway. And there is considerable evidence that the transition from spearmen to swordsmen within the Republican Roman Legio was prompted by meeting Spanish 'barbarian' tribal troops who were swordsmen with heavy javelins and big shields - 'proto-Legions', so to speak.
And, of course, the term 'legion' was used for all kinds of nonRoman troops and units right down to 1861 CE - Hampton's Legion of the Confederate Army in the US Civil War!
