SE has provided a phenominally ridiculous variety of different things to do in this game. I find most of them to be fun, and I'm glad for the variety. Variety is what an MMO SHOULD provide.

But, the downside of huge variety is that any specific activity is going to have only a small representation in the game, at least at first. For a player with only a few, specific interests, a good MMO is going to dry up VERY vast for them until it has a chance to grow and expand.

It sounds as though the OP is the latter type: there's only a few things they like to do in-game (endgame raiding being the primary), and there's not a whole lot of that available at the moment. My advice would be to either sit tight and wait for SE to add more content (the game's only a year old - there WILL be more content coming!), or expand your interests and explore some of the other content the game has to offer.

Leaving the game for another MMO is also an option - particularly for an MMO that's been around for five years or more. Those games will have had more of an opportunity to build a huge and robust endgame. I don't know enough about other MMOs to recommend one with a good endgame raiding community, but I'm sure there's one somewhere.
