Why is there a Push for End-game Content?

I logged on LotRO the other night, and Faced a Decision, I could Play Glinath and Try,Try,try to Level up.

Or.

I could Enjoy myself playing Agronia (Meh Hobbit Minstrel)

Then, I slapped myself. Why in World Do Developers Make Leveling up To 50 the Purpose?!?!
We should have enjoying your self along the way!
Now you are going to tell me that, "You can go to the Summer Festival!" or, "Maybe your just mad because you can't get a group for something"
I know! But, Racing or Drinking Something is Fun, But, I want Something "epic"
I Really like the Idea of WAR's public quests, Because, It something for you to Do!

Maybe I'm wrong, Maybe I'm Right..
