ok.. as i continued my work on the end game gear thread, I see what they did about glove cast speed.

Apprently IAS spawns on gloves, and rings.. and cast speed is amulet and rings. So melee and casters still only have 3 slots with speed boosts possible. If gloves were in place for casters they would get an additional slot.

Still doesnt explain why there isnt an orb to improve spell damage on caster weapons. I understand why the existing mechanic works the way it does.. my question is why do we have flawed mechanic that gives spell casters no other recourse to improve what is other ways a perfect wand with modest spell damage boosts equivalent to how quality improves melee dps.
