The only reason I would do it is that if you finish the valley of 4 winds storyline where you learn to punch with chi strikes and then finish the story in Karasang Wilds you end up looping back around to the wall and deal with the big bug that comes through the wall. Its a nifty animated cut scene but hardly on par with the eruption of the Sha of Anger from Jade forest. If you like animated cut scenes that is about the only reason for finishing the Karasang wilds.
That being said I felt a little underwelmed by how you end up dealing with the big bug, you cant even see what your character is doing. I would of preferred a single player quest 'dungeon' where you fight your way to vital points and apply your chi punch to them than what they gave us.
I mostly did this because the first time through I wanted to experience all the quests in a zone as possible. Now that I am leveling alts it is; 85-86.5 Jade Forest. 86.5-88 4 winds, 88-89 Tai long steppes, 89-90 Dread wastes. One of the villages near the great wall in Tai Long steppes has 2 gear vendors, one selling level 85+ gear and one selling level 88+ gear in case you find yourself lacking in an item. It is in the village were they are being attacked by Yuangtol invaders (ox men).
