To be an end game content? I dont see it being fun or interesting at all to be honest... In fact, it looks like an easy "omg we have no idea what to do so we will implement pvp and say its awesome end game content" kind of news to be honest.

For starters it will be stupid...slow targeting system...plus if you are in a party you will kick anyones butt with 0 problem...
I, for one, dont give a rat's butt about pvp and would like the devs to work on something MORE interesting for end-game content.
