Seems all suggestions are just for guilds and big groups to do things together and doesn't really give everyone a reason to world pvp. To make world pvp happen it is simple, you have to make it as convenient as a battle ground and award the same. Award 10 conquest points for every world pvp kill that happens when you kill someone your level or above. Split between groups if you are in a group. 1v1, you get 10. 10v1 each gets 1. 100v1, each gets 1. And if you kill someone below your level, you should lose 10, seriously, its no competition. Also no points for an afk, and no points for someone who is currently attacking another player. (honor can still be awarded as normal for all scenarios).
No conquest points = why bother.
Most world pvp currently are not much fun or gain for either side. Typically the aggressors try to find mismatches against AFKers, smaller groups, or much much much lower level opponents, who are clearly not spelled up or ready. No-contest for the wimp, and just annoying for the inferior defender. The best world PvP battles are those which both sides are contributing to and both sides have a chance of winning. Maybe hard-fought-long-even battles can award 100 conquest points.
No matter what we do, world PvP will always suck, but with conquest points award it'll happen more often and a tish more even. The reason we will never have good world PvP here like we had on retail is that the best world PvP on retail were on PvE realms. If a world PvP was happening, like a town being raided, a bunch of the same size and even a little lower level players would get ready, then turn on their PvP flag and join and it was epic. Impossible on a non PvE realm. It'll aways suck for 1 side, and the other side can hope for at best a tiny enjoyment.
