however, if you refuse to equip it then pvp probably should be a painful experience for you.
Painful experience = drop of subs. BW dont want losing subs only cuz some of pvp'ers have huge epeen ego and can be competitive only with their pvp gear advantage (and useless baddies without gear advantage).
Also, I don't understand the point of expertise at all right now.
Expertise is thing, which balanced all gear in WZ areas. Mainly, its expertise + endurance + mainstat + primary damage. Last, but not least, Conqueror min/max pvp gear is the best gear and wz and in the open world pvp. So, all pvp'ers have point for grind it for mains and for alts.
