Mages, all 12 of you. dd staff + ds = full exp?

[Tann]

just wondering 46+ does "spamming" the dd staff along with the global damage from a DS do enough to get full exp?

I am lazy when I play my mage and would rather just buff/heal pet, i'm fine with the 50% exp loss but wondering later on if the staff can cheese my way into the real business.
