Thanks. It didnt work exactly like you have done, because for some reason Makoto's Frei attack didn't drop the guy from the platform like it happened on your case. But i was able to do an additional critical on the ground mob and i eventually killed both. Then advanced to the next platform and performed the all attack. Then i had to kill one last guy behind using Makoto. But thanks, i was stuck for a hour on this mission, it's really stressful.
