I do agree, this is just an experiment, seeing what I can cook up with eldar allies. I personally like playing pure coven style dark elder lists. I don't even own any eldar models, so allies is a rather mute point for me. I really just wanted to experiment on how to make an already tough coven army even tougher. I am not very found of craftworld elder, and with the new codex coming out I am bound to not like them even more. I think dark elder should get the new codex, but we always get unfair treatment, such is life.
