Personally on the matter of the Space wolves i agree that they shouldn't have successors, and likewise the salamanders should be able to have Successors. As far as loyalist traitors. I believe that one could have individual characters that remained loyal, and maybe even stayed in service to the Imperium if their circumstance were good enough, but I have come to believe that having whole chapters based on the idea is dead wrong. Something that I am ashamed to bring up given that I participated in the creation of such Chapters when I was younger, and much more foolish (the shame!). As far as tech goes I agree that high tech isn't necessarily a bad thing for Xenos, but I am squeamish about those instances where they match or surpass Eldar tech. As far as human (or post-human) factions go I am firmly of the belief that they should not have technology that matches or exceeds that of the DAoT.
