OP it really depends on the proc itself and what everyone else values and what turns out to be the best with the gear. However like they said all gear will have a PvE and a PvP item level attached to them. PvP gear will have the highest PvP item level, while PvE gear will have the highest PvE item level. This means for example that Mythic gear might have X ilvl for PvE and like they said in the post a X-Y ilvl for PvP. Most PvE gear will scale DOWN in PvP, while ALL PvP gear will scale UP. This is because the tooltip will show the PvE item level from what I gathered.
The only way to balance this racial is to remove it or give it to everyone.
They have blue post on the front page of MMO stating that they are going to rethink PvP trinkets. With the addition of Ashram we might see some super fun trinkets. I think they have learned from the Legendary cape that PvE procs and PvP procs have to differ. I believe they will do more to assess the issue and prevent it from becoming a constant thing.
Though in the past PvE trinkets have always seemed more preferred. They added the resil boost to combat that I believe.
i really hope they don't make pvp trinkets like cunning and vial.
