I'm sure even the biggest Ray downplayers believe he pushes an emperor to mid diff minimum even at his age. Fucking Law pushed Teach to mid-high diff.
They be wildin with their anti-admirals agenda, but the same people who believed one emperor crew = Marine HQ + seven warlords for a whole decaded and got dogwalked by fake news Morgan about how Morley sent Fujitora to the hospital for 4 years are hardly the sharpest tools in the shed.
 
So what do you expect the big incident to be , ill go first it's nothing but luffy packing up a gorossei .No one ever dared to do that
My pure headcanon is that the big incident might be Luffy pulling an attack like Bajrang gun that destroys an admiral and the marine fleet in 1 blow. Since Saturn is in a ship, he may sink and this may trigger the final war.
