Portals and Hearthstones - Boosted Characters

I recently purchased the expansion pack - and I got the level 70 boost included. I decided on boosting a rogue because it seemed strong in 10.2 and I actually don’t have a leather class that I have collected a lot of transmogs on. I feel that it is odd that I cannot portal into Oribos, use my dalaran hearthstone toy, or use a garrison hearthstone without doing that content. It feels bad to go back and grind some random campaign intro for this stuff; which I think is exactly why the stones were made toys to begin with. Seems like it didn’t address the issue, just gave us 2 bag slots free?
