Ugh, this thread.
This is Zoro almost killed by Mr. 3, who was actually weaker than Mr. 4, the guy Usopp and Chopper beat.
This is Luffy getting trolled by Miss GoldenWeek.
Stuff like this happens all the time. However, they almost always succeed when it matters and the situation calls for them to.
If anything, I'm glad they are in the thick of things, fighting and getting battered. No one can say they didn't pull their weight once all of this is over.
