Would we be able to choose only one, we would've been able to analyze what brought us or keeps us to the game in the first place.
Fair enough that pretty much the Social, Killer, Explorer and Achiever mentalities are represented here by the players. Afterall its base is pretty much build after a mmorpg sandbox structure. Nice question nonetheless Dracu ... to see where the community stands more or less.
Interesting it is to see how many of us are looking forward to the exploring part nearly as much as the pvp part.
This game deserves the benefit of the doubt to press through with adventure and exploration, include Killers (pvper) into it Explorers (pvxer) won't mind, they are there to experience this exact game.
Add social players (pver) to it that will gossip about the game and its politics, minigames, craft and trade. Will they be killed they surely will leave more often but the pve game keeps em alive and so will the pvp flourish.
Then it looks like the achieving players that play the game to get all achievements no matter what seem to lack, hopefully this can be added to give a more pve/pvp content to keep the killers (pvper). With titles and stuff.
How much of it is needed of each area we can more or less see here to make the perfect balance of this game available for everyone and make the community happy. Coming from a gaming developer stand point of view.
Where we can progress and make the game more attractive.
