Yes and no, it depends on how we are playing. Usually each base is treated as a unit, grouped into four commands. In this game we grouped some bases into pairs for a unit. As there is no figure removal it really makes no difference. {It started here in GHQ partly to ease storage and make bases more like dioramas occasionally.} So far it has been used on my Late Romans, Republican Romans & Carthaginians, 1066, ECW & Crimean War armies. It also makes moving units about easier on the table unlike fiddly 40x40 bases we use for habit.
There is no point in being stupid if you don't show it!
