It does scale down. Crusader on my 19 is like 33 str, and 67str for my 39.
But what some twinks do is have three or four enchanted weapons, wait for a double crusader proc and then swap weapons to gain other weapon enchant procs.
I’ll gladly support the removal of this. It’s a general PvP exploit, not limited only to twinking.
Beyond that, welcome to PvP, think quick and harden up.
