But the actual point of the comment was to point out how SCH has a spammable Broil III at like 250 potency and SMN only has Ruin, 100 potency and a 15% chance to use Ruin IV which is only 200 potency...
But the dots hit harder, Fester has double the potency of Energy Drain, and you have a pet that's attacking too. Not to mention Tri Disaster buffs Ruin potency by 20 for 15 seconds.

Broil II may have 80 potency over Ruin III and 30 potency over Ruin IV, and that might feel bad, but there are other factors to take into consideration.
