Seriously, the "spam" factions need a "holding" advantage over the enemy. It seems logical to me that an advantage in having superior numbers should be the size itself. The blocking power, as it were.
It seems to me that once you're in melee, you shouldn't be able to run "through" an enemy formation. This rather exploit-like game mechanics gives a big advantageo to civs with higher quality troops, because there's can a bit too easily bypass a large number of lower quality troops by just running right through them.
As for calvary, I agree. They shouldn't be able to charge through a swath of enemies, just run through and charge again and again while taking essentially zero damage. It never worked like that in real life or in the movies either, so why here?
Also, calvary need I think to be taken down a notch or too. Currently, for many factions, their only counter for calvary is pikemen. Well, that's not too bad, except for the fact that calvary are essentially able to evade pikemen with ease thanks to their incredible charging abilities.
MoTW is a perfect exmaple. With their calvary, they can decimate enemy formations. Try bringing in pikemen and they'll either run around avoiding them or just use their uber-rangers to rip the pikemen to shreds. Simply put, there's nothing that can match that.
