even kaido was clashing with luffy using adv CoC i didnt see fodder flying, trees flying or ships capsizing or the island itself shaking.
Is it because Luffy isn't so strong?
Kaido collided with BIG MOM = paradise broke.
WB collided with SHANKS = paradise broke.
KAIDO collides with Luffy = Spread the clouds.
Do you first need to explain why Luffy and KAIDO clash and the sky doesn't break?
And we know KAIDO is capable of that.
Is it because one of the parts is weaker?
So, KAIDO CLASHing Luffy and not having the same result as WB and ROGER's CLASH means nothing.
