Ok, I must admit: I rushed my first toon to 100. Got the garrison to lvl 3 and all the buildings I wanted. No I mostly sit there, fill work orders, queue for HC to get the last few pieces of gear ... and thats it. I know I could do more like rares and apexis but I'm not in the mood for that.
Jumping on my main alt ^^
But leveling is a drag, really ... you basically have no choices at all with questing, and treasure hunting doesn't get you very far in terms of leveling, it's a nice bonus but nothing more.
And honestly: ANOTHER GARRISON? Managing the followers on my main is more than enough mini game for me.
You can't bypass the garrison ...
No alternate questing/leveling paths ...
That sucks.
