Game Mechanics: Weapon Procs (Spell limit)

[Treats]

Noticed this the other day while fighting Terror on a level 46 character.

About 50% of procs were landing with a Flux Bladed Axe.

Searched a bit but couldn't really find any information about this.

Should Weapon Procs adhere to the same 6 level limit that casted spells do?

As is now:

46 Ranger cannot cast any spells on a mob that is 53+
46 Ranger can land Weapon Procs on a mob that is 53+
