I have a question. Started playing as Rome, noticed that early roman units have insane stats compared to their counterparts. For example, early Hastati are at about 30 mil attack 40 mil def, Principles at about 40 mil attack 50 mil defence. Their main enemies, Samnite mercs and greek swordsmen are sitting at about 15 mil attack 20 mil def, Hoplites are even worse in that regard.
EG a unit of Hastati cuts through a more expensive unit with almost non-existant casualities.

Am i missing something hidden in the stats? Or its just roman early units being extremely overpowered?
