This is my first run of the game, and I probably have made a lot of mistakes, but I think they can be solved.

The Macedonians by now are pretty strong. They have about two armies with the banner almost filled and their capitol's banner is also almost filled.

I seem to have a problem fighting (And defeating) a large Macedonian army.
I usually engage or engaged with a typical roman army, I would think.
about 6 infantry units (preferably principes), 4 missile units (usually velites) and 4-5 cavalry units, including missile cav.

What I did with the samller armies I handeld until now is try to kill off their horses fast, and then lure their phalanx into an attack on my infantry so I can charge my horses in their rear.
This worked pretty well for me, until now.

Now this tactic doesn't work anymore.
My infantry can't kill off the horses fast enough, and the phalanx really messes them up.
My cavalry are torn between backing the infantry up against the enemy cav and attacking the phalanx, which are backed up by more enemy cav.

I've reached a good state for conquest, I think, but these Mac's are annoying.

Any help would be welcomed.
Thanks.
