I'm over the end of the MSQ, it's still boring for most of the cut-scene.

The thing is with not changing the content style and gameplay is that, it's the same content over the new expansions, some others MMO did well of changing their gameplay, keeping the usual content, but adding some more new ones.
I'm trying a lot of game, I come back here sometime, but this is the first time I get really bored by the game 1 day of getting back.

I agree with you, the game isn't for me anymore. Sadly.
