I was testing damage on the lvl 50 yellow dummy and noticed that my damage would go up after a weapon proc would go off, it didnt matter whether it was the offhand or mainhand that proc'd but the melee damage for both weapons would go up slightly.
Example: Mainhand hits for 114, offhand 41 ; MH 114, OH 41, offhand procs ; MH 120, OH 43; MH 120, OH 43; MH 120, OH 43.
I noticed this over several dozen hits using various styles and it was all the same pattern where damage would increase once an offensive weapon proc occured.
This might be something to do with the fact it is the free items and not necessarily the actual items in game with procs/weapons made by a character.
