Would his crew be with him?
no, he can not run from the three admiral
Well he kinda was able to run from them. Then Ace turned around and f*cked it all up.
So basically the question is Ace's pride didn't get in the way would he have lived?
First he would have used his conqueror's haki like he used it in the fish island ark...and knock out 50,000 of the soilders, that could have helped the allied pirates a lot and in the end make it easier to reach ace....
But give luffy a chance, he MUST go all out before the end pf the dressosa arc..
