Viper Tobi-Kadachi is actually the weakest to Thunder.

I agree that axing the Cave Wyverns and just barely replacing them with a brown Tobi-Kadachi was a weird move, however. The only reasons I could think of not adding them were because:

A) They had issues animating some of their attacks (such as the neck swipe or any attack that causes them to stretch.

B) They thought that any returning monster weaker than an apex was utterly worthless and undeserving of a spot in the expansion's roster.
