Am I missing something? After Ydra Forest, the next leveling spot is Kraag. But there's not enough content in there other than hauntlet and the crypts to fill the void to the next zone. Most of the quests are lowbie dailies or story dailies. Even in the AH after level 16, there's very little level 17-22 gear listed.

Now I managed to do Kraken Isles at 19 with another rogue bosses were one shotting us and we graveyard zerged it (probably went through like 200 health and mana potions).

TLDR: Ydra forest is too low, Kraken Isles is too high (getting one shotted). Did I miss something in between?
