Indeed, end game is not that interesting (I am talking from a pver point of view). Once a week, you pug BT and the short raids. If you have alts, rinse and repeat. Once a week, you do your VT and TT if you have a static group. If your alts are geared enough and have static groups, rinse and repeat. Every day you can do your 6 dungeons or so (the rest is made worthless, rewards-wise). If you have a group of friends around your level that play at the same time, or if you are made of rubber and don't mind a daily dose of drama, you can do them hard mode. If you are carefree, you do them normal mode. If you have alts and have any will to play left, rinse and repeat. Each 3-4 months, a couple more dungeons will be added and will replace some older ones, with some new accesories to bait you for a tiny bit higher stats.
BnS beautiful wide world ceases to exist as soon as you are out of the storyline. And since they removed the blue side quests, you don't ever see half of that world and there is literally nothing to do around that adds to the story, or to the feeling that you are in BnS world, or simply to entertain yourself.
End game is like pacing around in a very small cage.
Conclusion: Give us back the blue quests. Give us back something to do in BnS big (and now dead) world.
