World Simple (seemingly) Bow Id Addition

The on wynncraft clearly don't use the normal functionality (being reskinned wool etc), the velocity of the arrow is just assigned, why can't some bows have a higher velocity arrow (would make for further range and more accurate shooting) and some other bows could have lower accuracy/arrow velocity

 

One, this would be pretty hard to code.
Two, this would make some bows obsolete as no one would use them.
Three, they're all super-powerful! Even Earth bows are crossbows, which means that they fire a small quarrel even faster than an arrow. They're of equal flight speed.
