Jotaro is the best JoJo and there's nothing you can do about it faggot
Disabling Jotaro for over 10 volumes
Joseph had to get nerfed in Part 3 to let Jotaro be the hero, why are you complaining now that its happening to Jotaro?
Joseph at least was around
Jotaro wasn't even nerfed. He was out of the story for most of it because he'd be too powerful against most of the opponents there. He was past his prime, but he had an amazingly powerful stand and was clever on top of that. He's only weakness was in prioritizing his daughter's safety over defeating the enemy in front of him, and it cost him both times it happened.
Joseph on the other hand just forgot most of his skills and ended up only being relevant a few times outside of being the team bank account.
Why is Jolyne even trying to find Pucci after getting the disk instead of just delivering it the SWF
One part revenge and one part not knowing what he plans to do with the Green Baby.
How dumb. Jotaro would know what to do better.
Tranny
Yummy
All things considered, Jolyne and the gang actually did a pretty good job of tracking him down and taking out his reinforcements. They mainly just got really unlucky by crashing into the scene when Weather Report pretty much had Pucci dead to rights. If not for the dumb luck Pucci had in Jolyne, Hermes, and Versace showing up at the best possible time for him then he would've died and the story would've ended there.
There's really not much different Jotaro could've done to reach Pucci faster and deal with him. Hell, there's a good chance Jotaro would've been defeated at the hospital unless he thought of the same solution Jolyne did.
