The changes to the Eldar dex have done the same to my armies as the changes to the Chaos dex. Both have taken the particular flavour that I've enjoyed most and removed it. I really liked the small but elite Biel-Tan altered FOC, and I loved the old Rubric Terminators and Flamers. Both of my armies were well outnumbered, and often outgunned as well, but I did have quite a bit of fun with my theme driven armies. With the new dexes, I was forced to set the theme I enjoyed aside in order to field a 'legal' army. Both have been traded off in favor of armies that can legally support the vision I have for them. The Sororitas and Necrons will be, for me, what Eldar and Chaos can no longer be, legal armies designed for me by me, as it is my money and effort that pays for this hobby of mine.
