Yeah. IMO reduce the effect strength on the off-hand enchantment to 50% of normal or something, and / or remove the enchant proc that apparently happens on DoTs (which makes no sense to begin with, the rending slashes DoT is a bleed where the weapon isn´t even connecting to the opponent).
It´s fine that DW has 2 enchantment procs, but not 2 full power enchantments constantly procing on everything.
