At low lv (under 30 / 40 ) Builds make the difference (if eq is the same).

With same builds there is no way a bow can surpass a xbow as DPS.

Why? Simply cos Xbow has quite double weapon damage than bow. The aspd (attak speed) dont cover this gap. Bow aspd is not quite double than xbow.
Plus xbow, with his higher damage, got more damage bonus on enchant and has more crit rate (normal weapon, not Green one).

So if u seen a bow get aggro it'is because

1) different builds (maybe STR oriented)
2) different weapons (green weap with more crit or more base damage and enchant)
3) more skill spam.

That's all.

In the same condition xbow >> bow
