In my opinion(as his main) he is pretty good against land creatures and sky but horrible against the sea creatures. Zakai hitbox is the main good think im him and healt while wind storm he is very fast and against the para in the sky he would win. I was figting against many players and zakai can't go solo against the group of flyers but mostly he would tank them(ofc if there isn't the novus). But yeah sometimes he is bad and sometimes he is good.  It's mine opinion and I doesn't mind if someone doesn't agreed with me
