The thing about Roshi teams is the Roshi+Bee synergy and immunity to debuffs.

If you aren't strong enough to kill the Roshi on t1/t2 he basically counters every single team in the game. Theres nothing you can do to stop the ticking time bomb except stop his chase by going after the main.

I'm mostly talking about p2w here where you have him 65% mooded to be tankier, not arena where blitz can easily kill him. Permenant immunity to debuffs is cancer in a game where group composition and chase are supposed to be a key part of PvP.
