I don’t have his exact build, but what I can remember is him having cleric > priest (at least circle 2 for the auto revive in PvP and invincibility) > Paladin (unsure how many circles) > Plague Doctor (for the damage and anti-cc to go along with his near invincibility).
Of course, times have changed. The build probably isn’t as optimal as it can be for PvP, his build centered around not dying, or going invincible and reviving automatically, as well as having complete cc immunity and damage from incineration.
It’s definitely a good build for arena pvp, but I don’t think it’s all that great in the open world gvg.
