"He never let 2 people join in the same arc"

I don't think that criticism is very fair, since it was early in the series so there wasn't really a set "inclusion guideline". There still isn't, as there were countless characters Luffy tried to include in the Thriller Bark Arc.

Gin doesn't look much like a fighter. He's too normal-looking, and the best he's got is a gun. We actually see Sanji fight near the start of the Baratie Arc, so we know how he does his thing.
