There is plenty of the fun things to do at end game. Those who are bored usually are only focusing on one aspect of the game and get tired of it.

For me when I leveled I did not rush it, I took my time and enjoyed the story and watched all the cutscenes and enjoyed the trip to end game. Why would you rush through a game that you paid for and not enjoy it? I don't understand those people.

Take your time and enjoy the game, the most important thing is to have fun, don't listen to what others say. If you are having fun continue doing what your doing.
