Well, long time no see. If you want to play, so play to the end.
please before you try to argue this further, take one unit of preatorian cavalry and one unit of egyption chariots and have them charge each other, the chariots will crush the cavalry with only the loss of one or two chariots
Do you know why you lost only "one or two chariots"?
This is an amazing, hard to explain, unfair point of the "new chariot", which have...
10 Hit points (!!!!!) because of that, you didn't suffer from
the double rule: During the battle, your force will
decrease by the time, not because your stamina, because of
your unit loss. Because of that, your force will have a constant number to continue to fight, and the truth is 10 HP is too much (and actually not right compared with the history). This is the 1st point.
But to have... 10 HP, the chariots will not die easily, the force number remains constant over time. The chariot is too hard to maneuver,
it died right when cavalry born. It's why the defence of chariots is only 1.
But only the 10 HP is not enough for you to win. Because yours is only 18, but mine is 54. Your chariots will die massly if your defence is
actually 1, because follow that, only with 4 cavalry attack, your chariot will rout. And this is the 2nd unfair thing:
the experience. The truth on the battlefield, the better the first base, the easier the experience develop. But in this case,
the first base of chariot is too bad. It is heavy, hard to manoever, hard to fight constantly. But with the Rome rule, the experience raised freely, without concerning anything.
And to consume it, with some 5 or 6 experiences, your chariot will be a
formidable force: 6 or 7 DEF, very good attack (some 14 - 18 ATK!!!) and... 10 HP. That's why your force win easily.
To tell the truth, you have just only exploited some imbalance in the game.
