Game Mechanics: Weapon Proc Range

[Zeelot]

I've noticed that weapon procs do not go off as they should. Weapon proc range should be the same as max melee range, yet I often get the message "your target is too far away get closer" when I am fighting mobs unless I stand right next to the mob or inside it. This problem is most prominent with larger npcs such as giants, Ashenbone drakes in hate, etc. Levitate also causes procs to fail because of range.
