I have Han, Water Main, Roshi, Sailor Sakura and Cloud meta just destroys my team. Either Roshi dies in 1 round in Arena or Roshi dies round 1 in Arena against cloud team. (This was against LM though). Clearing buffs "help", but still need to get rid of the barrier which I haven't been able to do. Doesn't matter if Roshi is in Position 1 or 2.

But its a hit or miss when going into Ranked Arena, I got up to Super Kage rank going through 46-50 going back to 46. Capped at 54 though.

If you have more initiative than I do, then you should be fine.

You may have to go experimental Ninjutsu to counter Roshi dying in arena in round 1. But then you lose Poison Tai.

Isn't the goal of ranked arena to win, despite how long the battle last?
Would it still be fair to think Roshi's ignite would still do minimal damage while experimentation lets me heal every other round?
Experimentation also synergises with Sailor's mystery, and you can have an AoE healing every round as both of them heal every other round.
In what ways does your Roshi die by round 1?
Does he still die despite using experimentation?
How about SWB? Obviously, non-arena battles are a different story. Did you still get owned by cloud meta teams in SWB?
