Really, what possible argument against this is there? With the new set bonus system allowing bonuses for 2 set items, 3 set items, 4 set items, and 5 set items, running two separate items instead of two handed items allows more bonus potential.
There are 12 total slots for bonuses but only 11 if you're using two-handed. It can't be a difficult fix to change this, right?
The only substitute for victory is overkill.
