Exactly. The game's biggest problem right now is that there is very little incentive to log in and play every day. The vast majority of content is either one and done (most quests), a weekly thing that you can do in one day and be done for the week (raids, unreal, islands, etc), or so short and simple it barely even qualifies as an activity (tribalsociety dailies, custom deliveries, etc.)
Unless you're big into PvP, or going out of your way to chase some specific reward or achievement, what incentive does the average player -especially long time veterans who have done most of the one time things already- have to keep playing?
