Thank you

cav - arch army ratio depends on your preferences really, but from my personal experience its usually 1:2...
Max enhance your manual and donkey as a priority (max enhance everything else too).
And if you are using cav/arch your archers are supposed to kill the cats, the cav for inf/other cav/archers...
