:Here's an opinion from someone who knows very little about the topic:  it seems to me that the issue with the "Comancheria" section is that it is written with a focus on the Comancheria as a whole.  What makes sense in this article is to discuss how the Comancheria affected Spanish Texas.  Most of the text in the current "Comancheria" section either is or should be in the Comancheria article.  What's needed here is a discussion of the specific interactions between the Comancheria and Spanish Texas.
