I need a better Venetian stack

Personally i'd either drop most of the cavalry or all of the infantry.

I find that mixed armies often suffer from being the jack of all trades and the master of none, so it's sometimes easier to have both an all infantry (+ the general) and an all cavalry army operating at the same time; you can use either one as the situation demands...

You NEED to have a mixture - i.e a couple of cav units at the very least.
