yeah no one has gone all out in a long time besides Luffy. Zoro fighting Pica doesn't count. What happened to the fights where the two people were almost evenly matched in skill? Really Luffy didn't even go all out against Hody he just went all out on Noah and now Doffy. We really haven't seen anyone do anything and its starting to make me a little mad. I wanna see an arc similar to the enies Lobby arc where everyone was tested and there was a person for everyone to fight or start a fight and then run away, looking at Usopp here.

Just in Robins case she never really has fought anyone one on one that was worth mentioning. Her power gives her more of a "take out a bunch of weaklings at once power" unlike going one on one with someone.
