It's honestly hilarious how they basically went overboard with the multi-hit Limit Breaks to the point they gave no real incentive to the characters or even incentive to their later Limit Breaks for some characters.
There's no need to ever use Cosmo Memory or All Creation because Doom of the Living and Stardust Ray exists(and Yuffie's Conformer is so broken, it's not like the half damage deal would screw her over).
Really shows they did not even think of how broken Multi-hits are till like Final Fantasy IX and X.
