please give us something to stay in the game! (and keep keep the subscriptions up)

[DPZ2]

I'm not sure that SE can do anything to satisfy the OP. Then again, I'm not sure any company running an MMO can always make things "new and exciting" for longer-term subscribers.

If you look at the bare-bones architecture of an MMORPG you'll see the following:

story
questing
instanced and world group play
instanced and world PvP
crafting/gathering
gear rewards
achivements and rewards

How popular an MMORPG becomes depends on the story and the amount of instanced group play available. Eventually, you run out. For a non-MMO RPG you've basically 'finished' the game, after which you go play something else.

How to keep up a long-term relationship with an MMORPG? Take it in smaller chunks. Vary your routine with other MMOs. Play BnS for a bit. Play WoW, or TSW or SWOTR or Wildstar. If you're jumping between genres (JRPG, fantasy, scifi, horror, conspiracy-theory-as-daily life) you get the variety without becoming bored with any one of them.

Also realize that, eventually, you will become jaded. The shiny new-ness is no longer there -- for you. For the brand-new player it is still a shiny new toy.

Many posts I've read lately can be summarized as "This game would be so great, if only it were redesigned to be another game entirely". That might be a bit, um, optimistic. Another game entirely may not be exactly what you asked for, and many of the things you came to love about this game might not even be there.
