Gotta say I was always first a Carot fan but I really felt Oda put her too much on the side when Yamato was introduced. Now, everything's in the air. But the way Yamato didn't join was handle sucked, a lot.
I like most of Post-TS a lot, only Dressrosa is kind of a dud to me, Wano wasn't stellar but it was good. But that chapter is just average. Not terrible, after all new members of the crew aren't all there is to OP, not even the most important one. But Oda has to introduce the Eleventh member sooner rather than later for it to make sense story wise.
Right now we could end with the piece of shit Caribou for all we know !
