- 3 Non EA Corruptions = 27 ticks over 54 seconds, 3 GCDs to cast. If MG is 1 tick/s then over that time you get 54 ticks * .5 damage extra, or 27 'normal' ticks. Overall you get 54 ticks of damage.

Is 1 GCD worth 10.8 'normal' ticks of corruption over roughly a minute? No, because 1 GCD is worth 9 'normal' ticks of Corruption (via recasting).
