Haukke EX and Qarn EX. Gimme gimme gimme!

I also wouldn't mind seeing instances made out of the Beast Tribe strongholds. I KNOW they can do this. I get that their difficulty had to be nerfed, and are now much easier to traverse. However, I think I can speak for a lot of players who feel that these zones should be certain death for solo travelers. So create instances around them where you can indeed ramp up the difficulty, and force players to group to complete the objectives within. Could even have something like Prae where you are required to access the respective mount to burn down trash, or gain access other parts of the instance.

Make a quest and an NPC to unlock, glowy stuff shows up at the entrance, and done deal! Let's go SE. Chop chop!
