We were talking about the stagger effect which changes the timing of combos if you do it twice in a combo, not damage scaling.The stagger doesn't reduce the damage.

Aside from that, the point still stands, the game doesn't have proration.
Solo characters can kill of team characters in a single combo.It seems having the extra lifebar doesn't make up for an assist to cover your weak spots (especially when there's some ridiculous assists like Double's ass slam). I'm not sure yet if there's any advantage to using 3 characters??
