Particulary with casters and possibly with melee 2 handed weapons/casting items are generally less than desirable unless they are named items.
What I would like to see are a few boosts:
2 Handed weapons etc have a higher base than crafting 5 to begin with (easier to add some enchantments)
2 Handed weapons have some of the prefixes available as suffixes and vice versa so your wizard could have a +2 Necromany/Conjuration staff instead of 2 daggers etc and perhaps have some effects not available to 1 handed weapons such as arcane lore.
