TL;DR Khainite centric factions like Scourge and Har Ganeth should not have aversion towards each other(unless I'm missing some major lore point here), Scourge specifically should not have tolerance or positive relations with N'kari.(or chaos in genera

Not too long, totally read it:
Just some notes from last three campaigns where I've been playing Dark Elfs.

Noticed now, Scourge of Khaine has aversion towards Har Ganeth(makes no sense, should be opposite), but tolerance if not is downright buddy buddy with N'kari(likewise, makes no sense).That I'm fighting N'kari as Hellebron, is literally leading to conflict with them in my campaign now I can only avoid by bribing tf outta them. If were Morathi, sure, but fellow Khainites? I dunno davy.

This leads to them being seduced 100% of the time as they just sit there while Slaneesh agents give them the mark and inevitably ends in their vassalage.

N'kari in general pretty op with this, united all elven factions in western side of the map against me in the chaos invasion had going from dynamic disasters(thus meaning entire western half of the map was allied with chaos too as their vassals, was a fun end times lol), now this is not this mod's issue specifically(have feeling going to be a nerf for how easy slaneesh can do this coming in 3.0) but I really feel like if Scourge would just fight with them, it would at least offset this more.

Anywho, my two cents for balancing that.
