Can anyone do a check and see if the mobs themselves are changed? As far as I remember, ALL of WC was a maze (be a shame to see it nerfed), so I don't know which part is being "removed."Wailing Caverns * The maze section has been removed, and nearby creatures and bosses have been adjusted to compensate.
I THINK that the only unique mob there is the Deviate Coiler Hatchling outside the instance, which somehow has been shown to be of a slightly different color to other orange wind serpents. However, quite a few pets--like the white or purple snakes--are only available to low-level players here.
If the section with cobras were removed, then, this would mean that the Serpent family would go from being first available to level ~18s to being first available to level ~40s.
