Heroic: The Everbloom

There is a way to get to Yalnu and skip all bosses except for Archmage Sol.

This works for both regular Everbloom as well as Heroic.

When entering, go to the right instead of left as if you were going for Witherbark. On the left side of the path, there is a hut. Kill everything in front of and in it. Go out the back of the hut, and go to the left. There is a way up the cliff that spills you out onto the Kirin Tor section of the Everbloom. Kill Archmage Sol, and the gate will open to Yalnu.

This is also a great way to bypass a lot of trash even if you want to kill all the bosses. Just drop down to the path on the right side of the cliff if you want the ancient protectors. and Xeri'Tac after killing Witherbark.
