that is true, they are mortal, they are not Dante from Devil May Cry and hundreds of bullets that he spends but they are more magical weapons than the one we have.
There isn’t even a Gunslinger as a spec, and we can’t use 2 pistols as a hunter’s weapon, and as fantasy as the game is, the MMO had something realistic about it, so it was fun for the hunter to control his ammo in his inventory.
As well as other items that disappeared like Thrown weapons for Warriors and Rogues, totems and anhks for shamans, relics for pallys, seeds for druids, poison for rogues, sigils for DK’s and souls for Warlocks.
