In my current SP v1.2 campaign every battle I play until, oh, about 230 or so BC will end in an epic cavalry charge. Im playin' Saka, so every FM I've got and whatever cheap HA's I can (barely) afford until I take W India makes up my Army. Saka BGs are freakin' tanks though, perfect for surround-n-pound, pretty much the only way to rid yourself of annoying phalanxes.
