I do understand some basic ideas: the higher the level, the more you can do.
But I'm also reading a lot of complaints about how there's little to do at "the end".
So, why try to get there so fast?
Admittedly, the post linked above asks how to get through level 10 quickly because it's a slow crawl. Maybe that's meant for experienced players because they've gone through it once already?
As a new player, I'm slowly getting it done myself. I don;t have hours to devote to the game weekly for various reasons and maybe my lack of play time is forcing me to temper what I am doing or going through in-game. I guess I think the journey is more important than the destination here.
