as for cav being packed over top of one another....... thats easy to beat so who cares.... as for spamming one unit... thats easy to beat so who cares....

u NEED 5 max
-without it parthian armies are way overpowered..... especially in 4v4 games were 1 player can get parthia and get like 10 camels cats and archers and then have his allies cover parthia with there inf... then parthia will rape anythign that comes into contact with it..... u NEED 5 max rules

without it
selic is overpowered
armenia is overpowered
parthia is overpowered
greek is overpowered
scythia is overpowered
and a few others

and its not just about cav
5 max prevents sumone from getting greek in a 3v3 or 4v4 game and getting loads of spears and using that for there inf.... then there allies getting loads of cav... ive seen it done before.... and it is cheap

5 max prevents so many things...... true it doesnt stop every cheap noob army out there but it sure does stop alot of them
