Robby and Kwon should have been Finals

Robby vs Kwon was arguably the best rivalry in s6. And in part 1, people were more hyped for kwon to be main villain than axel ever has.

S6 part 2 can go similar, but have Iron Dragons and Miyagi do face in elimination rounds, with miyago teaming well and with final blow miguel beating axel.

Also the lesson Miguel learnt which he kinda learnt in part 2 but was scrapped in p3 that he doesn't need to win every battle for team (like he needed to in s1 and 4)

Robby and Kwon fight in the finals, on a closer match, with the 2 best choreographed male actors. The other plot points can also be altered too.

If the writers desperately wanted another brawl, they can have after robby celebrates, he is attacked by kwon, brawl happens the same, with Axel redeeming himself to save Sam, and severely injure kwon, getting him banned from international karate, but redeemed in eyes of miyago do.

Then Miyagi do can celebrate their win at All Valley in front of crowd, before an epilogue of the next all valley with Devon, Kenny and Anthony.
