Currently, a character who dual wields or uses a 1h+shield setup has a potential of 12 set bonus slots (7 from armor, 2 from weapons, and 3 from jewelry). In contrast, all two handed weapons (including bows, restoration staffs, and destruction staffs) only have 11 set bonus slots, as their weapon takes up both the main hand and offhand slots.
A dual wield or 1h+shield character can use, for example (and not including jewelry), a 5 piece set and a 4 piece set at the same time, or three 3 piece sets. The two handed lines can only use a 5/3 or 4/4 setup.
I think the simplest way to correct this would be to make all 2handed weapons (including bows and staves) count as two items towards a set bonus.
