There's one last issue that needs to be brought up. For the love of me I don't know why it has to be brought up, but I have seen enough debates on it for this issue to bear mentioning. That my friends is Chapters with Chimeric Gene-Seed (Multiple forefathers). Now please note that I see no reason why these Chapter shouldn't exist. The Mentors and Relictors for instance are both state as having Gene-Seed from multiple sources. I will say however that I don't approve of people using mutliple Gene-seed sources and then making Chapters that are basically just hybrids of the Chapters they were born from. I also think that if mixed Gene-seed Chapters shoulkd be allowed to continue then only the most stable Gene-lineages should be used. Gene-seed is prone to mutation, and adding extremely diverse Geneseed would likely only make the job of keeping it pure harder.
