And why don't just ban the prisoner of the arena and let him alone ? At least we can still use him in pve (for the dungeons) ^^
Make his passive as a beneficial effect (counter by immunity) AND works for 50% is too huge!
One or the other would have been a correct adjustement, not ?
(i don't care about use him in pvp, i have other characters with great skills to test in pvp! I just don't want seeing the most valuable character in the game to become a shitty one lol)
