For a frame of reference, SMN and SCH have their own AoE around caster with DoT ability, Miasma II, which has a whopping total potency of 70.

But the potency is from DoT, if you're spamming it for the initial damage, the DoT keeps resetting, so it's not as much potency as you think. Right now, people Blizz 2 spam adds after debuffs/heals are up, so it's not as drastic of a potency increase as you think.
