There's a bit of debate regarding the Elohim, the Tolerant trait and the unusual combinations it allows for. I must admit, I didn't think that the Elohim were particularly suited to the Assimilation role and it felt a little like they were given it because it didn't fit too well elsewhere and that they "needed something".
I've been taking part in a discussion in
this thread that has generated a few interesting ideas and I've got a fairly decent picture in mind of how I'd like to re-implement them (see that thread for the details).
The other side of this is that the Tolerant trait would be re-branded to something more conquest oriented and temporarily assigned to Decius. By his own claim, "thrones sit easily beneath him" and his presence as leader of three (very) different civilizations suggests that his talents are in leadership rather than pursuing a racial agenda. He would lorewise seem quite happy to use warriors, zealots or vampires as suits his needs and probably any other units that come to his hand.
I say temporarily because I had planned a civ that fulfills this role (and also was a 4th option for Decius to lead, along with the natural leader) for a later version. The more I think about it however, the more it seems to work with Decius.

Any thoughts on this are appreciated - I'm sure there'll be a few...
