We are talking about this patch, not previous ones. Even though your statistics are irrelevant for balance, your statistics are old and not about this patch. Check the date, june 03.
And yes, not 80% is crossbower lol. But crossbows definatly deal too much damage in one shot and they definatly lack any need of weapon points for dealing damage.
Sorry, but you cannot simply say they are irrelevant. You must give a reason for this bias assertion. Please explain, if crossbows are so absurdly overpowered, if they kill in one shot all the time, why then do they only account for a meagre 5% of deaths?
Explain it. Furthermore, the fact that this data is over a month old does not detract from it's value. The only change I can recall from the 9th of june to crossbows, is a removal of speed bonus from heirloom. So explain, please, why statistics taken today would be radically different? Granted, bows may be, but crossbows . . . I severely doubt it.
An arbalest should have the capacity to kill in one shot. Otherwise, you remove it from the game. If it can only kill in two, then it is rendered obsolete by the faster heavy crossbow, which can also kill in two shots (and then even the crossbow). I have been shot from 15m by a masterwork arbalest using masterwork bolts. I lived, with 44 body armour, 15 strength and 0 Ironflesh. Using an arbalest, I have shot, and merely wounded a peasant wearing a Nobleman's Outfit. At 10m. The damage of this weapon is absurdly varied, and so it should be. If someone invests 6 heirlooms into a single weapon, I do not think it absurd to grant that weapon a certain level of lethality.
With my 44 body armour, I am frequently 1hit killed in melee. I do not come on here and bleat like a fat ewe. I accept it. My character invested heavily in ranged ability, and as a result, my melee survivability is limited. I imagine you are the type of person who thinks that there should be no trade off to investing nothing in shield? Well there is, you get shot more. Balance. You trade some survivability for melee lethality. I trade melee lethality for ranged lethality. Furthermore, melee lethality is not entirely nullified by 4 points in shield and half a brain to point in the right direction.
