Everyone's jumping the gun tbh
We don't have enough context to definitively say whether this is a good or bad thing for anyone
How old was Rocks? How long was the battle? Did he get any help? How strong was the Admiral?
If I'm being honest I don't really see how it could be framed as a positive or negative for any agenda anyway
Rocks is probably the strongest pirate ever barring Joyboy
If Rocks is > any Yonko that's ever lived how does this help or hurt the Yonko agenda? Everything stays the same
