United Kingdoms

That is, against lightly armored trash mobs, a bow is better.

Only if you've fully invested in the specialization.

Secondly, the bow has a higher chance to hit, due to the number of attacks.

It's just one additional attack.

And finally, the bonuses from shamanism/Ixianism/Menas/hunter.

They are not needed by the crossbowman.

No one is arguing that you can find many examples of BUT AGAINST TARGETS WITHOUT ARMOR, IT'S GREAT!, but the problem is that against targets with armor, it will be completely ineffective, and the crossbowman will take them down, albeit not as quickly, even without armor.
