Correct me if I am mistaken but the new Tyranid Codex feels woefully incomplete and seems to have just invalided most fluff rules that were presented in the 5th edition FAQ
Like can your Tyranids now use emplaced weapons and occupy fortifications. I saw nothing in the rules to specify otherwise
Its details like these and making no effort to address Tyranids lack on an allied detachment that left me feeling a little meh about this codex more so than any unit or wargear changes, it just felt like new profiles were created for new models, and the book was pushed out with the least amount of thought possible.
