I'm just wondering when this content starts to get fun?

If you're not having fun now, then you're probably not going to have fun at all. Unless you're into even more soul-crushing grinding and bunnies that will lead you to your death.
The "NM Train" is going to be your fastest way to level and get the tokens you need for your gear. Not sure if it's still kicking though.
