So general consensus are that GP10 quints are not worth while, neither is the GP10 in utility masteries? I take it your getting your gold off of the items then? either the spell thief or the coin? or is it just the kills/assists you are getting from being an AP champ?
Items and kills / assists. I tend to do OK in laning phase even i fail mid game so I'm not usually starved for gold. It could be a problem if your lane is really passive I guess but I haven't seen many passive lanes in season 4.
