On top of the fact that the single AoE did 20% of total damage required instead of only 4%.
Simple example would be 5* 100hp instead of 1*500 hp, with a 20pt AoE. That leaves you with 5*80hp vs 1*480hp.
(Hit points don't actually scale that way of course, since they're counterbalanced by other action economy factors.)
