It is really important to have servers who caters to PvE / PvP player, because we want totally diffrent things when we play.
Warhammer online and Aion must be the best pvp games i have everyplayed in my life.
I would love to see Warhammer online alike world pvp, while i want arenas, 1v1/2vs2/3v3. 1VS1 arena because i dont care if it is unbalanced or not, i want a place where i can alone train my skills in pvp for some kind of small reward, even if it is just raiting. battlegrounds are fun, but world pvp with objectives is the most fun of it all.
It is really important to have world pvp where people need to do it for something, if you only have the option, but you wont get anything out of it, then people will just not do it. Rewards!
I know i say look at Warhammer online, over and over again, but to be fair, they really nailed the pvp aspect, every tier had some kind of pvp, if it was hold some point, capture points, controll keep ( attack/defend ) with ballistas, cannons, and drop oil on the ppl who try to destroy the door on the keep, had Witch Hunters/Witch Elfs ( assassin/rogue class ) who had a skill so you could bypass a backdoor and enter the keep and ambush the enemys. any way i talk to much. But i just trying to say, every tier, had 1 place where pvp where at thing. They had something called " Warcamp " it is kinda of a PvP hub, then you could take repeat quest there, go out and dp the world pvp objectives and then go and collect your reward. then there were also normal quest hubs ofc.
Anyhow, Warhammer is the best pvp game, if you can check it out, do it!
