Exactly what the title says.
Common and uncommon items are not that hard to find for the reforging.
Since the AP scaling actually favours the higher tier items, I was thinking what would make common and unocmmons more "worthwhile".
My solution: make them more comfortable. They shouldn't need to get reforged and loose duration.
That would make those items far more interesting for PVE.
If we don't unequip them upon reaching 0 duration but only "deactivate" them you would also save the time of equipping them again (Something I would also really like for fallen heroes).
