Defense in PVP. Just place 5 recovery legends specializing in defense. Very simple. You win by running out of time. Legends is ruler.
That it.

@young schooner some of players suggested to use heroes with heal prohibiton chatacters. I do not know is that enough.

Vs 5 tanky healer... Probably not.
But there's several aoe heal. Prohibition.. Or even a single. Hero that does healing reverse (basically damages for the heal received)... And he is the only one. (necro)
If you get that one you basically counter any party with heal they almost one-shot themselves or close enough.
