Attack Speed and Projectile Speed

What is the major difference? The time between when the arrow leaves the bow or the speed at which the bolt fly's?

It really only matters with skills where the projectile vanishes after a certain distance. a 40% increase to proectile speed can make them go up to three times as far occasionally.

So which is better or more useful?

Generally Attack Speed. There is a -few- exceptions, but for the most part attack speed serves better.

proj speed gives range

attack speed gives, well attack speed

I want a unique which has:

500% projectile range (to counteract reduced proj. speed)
80% reduced projectile speed
40% increased projectile damage
20% increased skill radius


Projectiles move 5 times slower but the same distance. Have a bigger AoE and more damage.

Thank you all for the replies.

Projectile speed doesn't give range expect for a few skills. projectile speed reduces the amount of time the projectile needs to hit the enemy. It's not even comparable to attack speed since they do completely different things.
