Chaos allegiance - everchosen battalion?

[MaxPounder]

With the changes to battalions is it possibly to take plague touched warband in a chaos allegiance army? 

Or does everything in that battalion still need the everchosen keyword?

You can take the plague touched but it would have to be an ally battalion though only what doesn’t have the Slave tag would count as allies

Grand Alliance Chaos is not a problem. There is a Question in the Core Rule FAQ:

Quote

Q: The rules say that a warscroll battalion can include allies
and that they don’t count against the number of allies in the
army. Does this rule only apply to battalions that share the
same allegiance as the army, but that have units from two
different factions (a battalion in a Daughters of Khaine army
that has Daughters of Khaine and Stormcast Eternals units,
for example)?
A: Yes. The faction a warscroll battalion belongs to is
shown on its warscroll, above the title of the battalion.
In addition, the battalion is assumed to belong to the
Grand Alliance that its faction is a part of. Warscroll
battalions that share the same allegiance as an army
can always be taken as part of the army, and if they
include any allied units, these units do not count against
the limits on the number of allies the army can have
(or against the points limit that can be spent on allies
in a Pitched Battle). An army can include a warscroll
battalion of a different allegiance to the rest of the
army, but if it does so the units in it do count against the
limits on the number of allies the army can have (and
the points for the battalion and the units in it count
against the points limit that can be spent on allies in a
Pitched Battle).

In case of any other allegiance, what @King Taloren said.

A main problem with Everchosen is, that the Battalions aren't even useable outside of the Grand Alliance, because since the rules where changed in 2.0 that units, not having the Everchosen Keyword would still be allies in a Everchosen Army (with the difference that they don't count against the limit) instead of becoming part of the Allegiance  (and only restricted not able to use Abilities) like it was before 2.0.

Everchosen really needs an update, like with Beasts of Chaos, giving the units inside the Battalion the Everchosen Keyword or a new Battletome.
