Many times did Luffy have worse haki than his opponents, yet broke through their defences because his physical strength was stronger than their haki defence.
Seems like people are forgetting how important physical strength is. Is the best stat for Kaido, BM and Luffy...along with their haki.
Stop sleeping on Burgess. As long as he has basic hardening (which he does) his attacks will be devastating. If he has strong CoA.....the OPverse is finished.
