Some people don't realize that crossbows max out at only 3 attacks in a round, unlike the 7 a bow gets. You also have to spend two feats to even get those 3 attacks and at a -2 attack penalty. 1 shot volley crossbow vs. 3 shot volley with a bow. That's not counting having to get the sniper feats. The Sniper feat evens things out, it in no way allows an advantage over a Bow, so should not be a factor here.Crossbows have the crossbow sniper feats.
I understand medieval history. Unless we start removing the ability to master anything that can double as a farm tool, or making rules where swords do less damage to full plate and only nobles should use them, the history on the nature of a weapon has less a factor in a fantasy world where Orc run around with an axe the size of a full grown cow lol.
My reasoning is the class' theme is simple, precision shooting, how does Cross"bow" sniper not fit such sharp shooting? I'm honestly surprised this would be a problem, it's not like there's a balance issue or any stretch in reasoning. Why make a new class when adding two feat options is easy.
