Also I want to say,
Recently, I have tested a xbow and bow in Scout/Warden,
xbow ( 3.5 speed, 94.2 dps) approx 352 dmg (not certain but has more dmg)
bow ( 2.5 speed, 97.5 dps) approx 232 dmg
xbow outperformed bow, in 1min fight with buffs(essance, blood arrow ...) and w.o buffs
xbow is better if you use ONLY shot and auto-shot,
It is because all of scout's skills are based on ranged weapon dps
