Crossbows however are overpowered in my book, I'm not gonna restate facts that were already given, but crossbows atm are the best ranged class in my opinion. They deal too much damage for the accuracy that is given to them, and the heirlooms are just making it more insane. Take the pictures in the OP into account with +13 pierce damage from a loomed arbalest+steel bolts. You don't see those numbers on any of the other ranged classes.

I will even expand on this. As the op stated, an archer can fire 18 shots per minute. An xbowman, 8.
8*100p = 800p per minute. = 13.3dps
18*77p =
1386p per minute. = 23.1dps
