I think the weakness is that there not any reason to team up with friends Guildmates or whatever so this game does feel more like a solo adventure game and the players that walks around the maps could might aswell be npc's playing for that matter. If there was a few dungeons or whatever it would have done so much ... Is not that the expansion is bad but it dosent give you this where you can say hello friends we gotta work hard and really teamwork to make this happen and is just a shame ..
