Do not get sucked into doing the "A Little Patience" scenario. It is not part of the campaign or storylines you need for the remix Landfall achievement. It is a daily, and you will not need it for rep for Landfall , you will get exalted along the way of the campaign. We used to run this in a 5-man scenario group iirc.

Though long chains, you can shorten it and/or make a bit more tolerable by doing the following:

1. 
   
2. Set your Heartstone in Lion's Landing/Domination Point.
3. 
   
4. Take the flight point to your destination whenever it's available for some additional lore.
5. 
   

You can Heartstone back to resume the chain and then take the flight point, giving you the opportunity for a small break and cooling down the Heartstone a bit more. Don't fault the devs for keeping this in as is, it was a reputation-locked chain that's now unlocked start to finish due to increased rep gains. I understand that they don't want to redo the whole chain for Remix alone.
