i would think you would have no problems with chariots as rome. my big problem in my campaign are the bloody thracian onagers. the damn bitches keep kicking my butt. maybe one porblem is that i'm almost always outnumbered by 1500 men. but back too the point. save your pilas fpr the chariots and you'll kick but.

a tip lure them into a attack and then use this formation



/S/[P] [P] [P] [P]\S\
/S/ [P] [P] [P] [P] \S\
[A] [A]

P = LEGIONARIES/ PILUM THROWING INFANTRY
S = SPEARMAN
A = ARCHERS

the rest can be filled in by yourself. put you soldiers on guardmode and turn fire at will on
