Wind in 4.0 was boosted because was blatantly the worst main before.

About the issue with han... there's no issue. lightning treasure blitz team just flat out dies to han roshi sailor sakura af version as it used to do before, both with earth main and mb. You stand a chance only with ay 4th in ay 3rd place and only if the enemy af isn't mooded hp (on par power).

Han removes and has always removed only temporary buffs, so in ay 3rd, samui, darui, earth main lineup removes samui boost, removes pose of duel buff because clears the shields but don't remove ay self buff given by high chakra and doesn't remove darui barrier boost because is not a buff.
