Every team and every class has its counter.
From the looks of it you are running a WB asuma, Darui, Iruka LM * or an equivalent one. which is easily countered by reducing main's att even 1 point under full hp.

Most likely this kind of team runs the double standard attack instead of root, which will make it so vulnerable.
I had a fight with a higher level in my group using that, true he killed chojuro first round .. but he got reck all over second round.

I find water main the most balanced Class (for now) and i run the Mei Chojuro Ao meta ...

And to be honest, LM needs some changements, it kills the fun of the game :D

I have Mifune, Danzo, ... i can make those Lightning metas but imo there's no fun in that.
