I never touched MWDA or AOD or whatever it should be called, but one thing that has struck me as curious is how some units that are traditionally associated with a certain faction or factions within BattleTech, those factions don't appear to have access to those same units in MWDA. For example, as far as I can tell, House Davion doesn't get the Cavalier, a unit that's only built in the Suns in the current era and there doesn't appear to be any of their factories changing hands during the Dark Age, so its distribution baffled me when I was researching for the Cavalier's BAotW article.
Were MWDA units and their faction availability fixed in stone, or was there any explanation for oddities like the above?
