Yeah, sure, hokage minato is bad in 1vs1... That's the reason why in top swb fields if there's a minato is hokage, because 130k+ people like to go in with subpar options.

The team you faced works but requires high playing skills and an overstacked move 1. A 70k hokage minato with two stacks of selfbuff literally lands twice the damage jonin minato does in the same situation and also grants +40% resistance to the whole team. The reason why your enemy lineup do not work is bad playing skills and too low bp on hokage minato.

Right now, actually, hokage minato is one of the best options as the 3rd ninja to add to kisame samehada + angel god konan lineups and is so exactly because of his passive + his insanely high tai attack that is what misses in that team.
