There are two options here:
1- Crossbow:
t10 +6
Physical Damage = 1230.5 (DPS 395.7)
Attack Speed = 3.1
+932.4 Patt
-----------------------------------------------------------------
2- Bow:
t10 +6
Physical Damage = 920.3 (DPS 381.9)
Attack Speed = 2.4
+511.2 Patt
Which one of these you choose ?
I think xbow is much better for killing bosses and trash,
and probably I will have more damage in boss fights with that crossbow
What do you think ?
