I've been thinking the same thing. Planet based pvp events where we all hash out rules. I think player-based planet control would be fun .It wouldn't eliminate lowbies from leveling, but it would be fun to work out some deals imp/pub and take this game into our hands even if the Devs don't do anything about world pvp... we the players should. I think we could turn the dune sea into a battlefield easily, it feeds in troops regularly due to the outposts. Idk bro, but I've been wanting to post about this for a while and saw your post.
There was a huge world PVP event like that on Jung Ma. Im talking battles of over 50 players on each faction across 2 planets with actual objectives. I can find the link to the thread on that sometime later but it worked pretty awesome.
It would definitely be cool to start something up. There was a pretty good duelling tournament several months back but nothing since that ive known about.
