If Timberline Falls ever gets updated I'd like to see the Krait events turned into a more coordinated meta event. Upgrade the Krait Witch event to a world boss or least a legendary. Change the tower to give platforms with champs on lower levels and a broad platform for the witch at the top. Add a new type of storm swirling wind vortex around it that affects gliders and griffons by spinning them out of the area.
Remove the vines and downplay or remove the risen on the map except what's in the personal story to make the map more focused on the Krait in the south east. They really are a tiny fraction of the map anyway. The swamp could become a Krait Spawning grounds event kicking off the meta. It would make the map time period more generic.
