At lv.45 no reliable way to get Prestige points outside of dailies.

[Masqava]

It gives no real incentive to PvP in open world, cause you get literally nothing for it, you get no contribution points, no prestige points, nothing.

The only way to get them is bosses you need an enormous amount of people for, so it doesn't really give people a reason to kill each other as they don't get anything from it anyways.

They might aswell just kill lowbies that farm prestige points and get more out of it...
