20% of the mages arcane blasts procced the staff, so he got 20 extra arcane blasts. 20% of your DoT ticks procced the staff, meaning you got 100 extra DoT ticks.
From here, it's a matter of how much the DoT ticks actually do for damage compared to a single arcane blast. If an arcane blast does 20k damage and each DoT tick does 1k damage, then the arcane mage gets an extra 400,000 damage while you got an extra 100,000. If the numbers are similar to this, then yes, the arcane mage gets more benefit.
However, if the arcane mage's blast does 20k damage compared to your DoTs doing 5k damage, then he gets 400,000 extra damage while you get 500,000 extra damage. A clear win for you.
