Since obviously the developers did not make this a sandbox full loot pvp mmorpg. They chose the wow everquest darkage of camelot route okay. But I hope they realize why dark of camelot was a amazing pvp game. It wasn't the 3 faction design. It was that you could attack anyone on your faction on select servers, the awesome rewards for pvping in stats etc, and the games fun tho somewhat unbalanced mechanics of it that some races would have fast movement speed and some classes could hold up in a building with a pet. But PRIMARILY it was that you can attack anyone from your faction outside of towns.
If this game does not want to be another cookie cutter mmorpg and catastrophic failure the likes of warhammer online in fan expectations. It will have ffa pvp. There is absolutely no reason to not wanting to have the best of traditional mmorpg pvp design in your game unless you are complete goofs.
