to be fair RTW was way better than RTW2, up until like the last DLC when they finally fixed everything. Everything but the squalor -- my god, so much squalor. 

Idunno if fire arrows were anti-cav in Rome 1, mainly because I mostly played the Europa Barbarosa mod and that changed like every mechanic in the game right down to the map. EB went all the way to India and they brought in Timurids, which was basically the full Attila experience like a decade before Attila happened.
