Useless or redundant units?

[calmon]

Just some comments to the Arco Chariot Archers:

They are quite usefull because after taking the 10 damage (full hitpoints) only the archer dies and the chariot still attack with the charioteer and have another 10 hitpoints!

The best thing is after the battle the chariot is full repaired and has a new archer.

The normal chariot has a better protection but die after 10 damage.

I use both units and especially the archer chariots. The good defence, the acceptable protection and the 2 Lifes make them extremly powerfull in early game. They tremple independent forces all in ground and lost nothing most of the time.
