Now that I think about ... there may be good reasons for why Nergigante doesn't fight or go against Vaal and Kirin.

Vaal's effluvium can probably counter Nergi's regeneration... too risky.

Kirin thunder powers are a menace to Nergigante, also it will be a small prey compared to other Elders.

In the end I guess that Kushala and Teostra are more common, safe and best meals for Nergi.
