I'm also quite interested in Apsod's application.
But seriously, decreasing missile speed for bows is actually going to make archery more luck based, than skill based.
Poorer missile speed means less range, and to compensate for this, wider arc (aiming higher), and so, very easy to dodge. After shooting your arrow, you'll just have to pray for 5second that your target doesn't move, or moves in the direction you want to, for the amount of feet you guessed, to actually hit. Wich will just be pure luck. Increasing your accuracy won't mean that much, since a lot of other criteria influence it, whereas there's only PD for missile speed (if i'm not mistaken).
At this precise moment, my main concern with archery is the greater missile speed for low tier bows. Since they're already more accurate, and we have a huge damage boost for headshots, it's actually "more" viable to go around with a cheap nomad bow, than with a rus bow. Wich doesn't make any sense, price wise.
I thought price were supposed to reflect the effectiveness of the weapon, wich doesn't really work with archery (only bodkin arrows being way more expensive than tatar makes sense).
Wich was also why i really hate the rondel+shield builds (and now long dagger+shield), since it's very cheap (close to leeching cost) and yet very effective.
