Hmmm I wonder why? Players don't get rewarded with anything so they have no reason to.
Lol what?? Right at the end of the run a screen pops up that gives you the option to add the players you ran with to your friends list
Very linear story? You mean each class having it's own class story that different from each other as opposed to say, WoW, where everyone does the exact same quests no matter what class?
This is what todays players want. We are in the generation of, " it's not a job but a game" crowd of players
Again, generation of, "It's not a job and I only have limited time to play so give everything to me now crowd"
This is not SWG, go play a shooter if you want arena. world pvp will never happen until the developers start handing gear out like candy, not exactly sure what you mean by cross story.
