With the new 2.0 update, I believe wind main talents are very strong atm and very versatile.
Sage Art Sand Dust will dispel all enemy debuffs first round.
You can run dance of impetus to reset cooldowns and for double heals for sailor sakura.
Mei is there for control. Chase on knockdown and insane mystery and the field is nice.. mostly used to cancel out the enemies if they have a field.
Overall, this is a very tanky and controlling line up. I would use Gaara instead of Mei but I found it hard to make combos with gaara, and Mei can be used on the third turn.. much more valuable.
