Reasons for doing black legion include:
- I like the fluff of black legion. I really like the idea of a bunch of guys who have been around for 10k years and want to burn everything they once worked to create now that they can't have it.
- It allows me to include units from various powers that would otherwise be unlikely to get on together
- I think I can do black that looks good.
- The studio ones are rubbish and don't look properly evil at all. I haven't really done an evil army before and I think it could be fun.
There are some interesting variant schemes for black legion in the chaos book that I'll take a look at. I'll do some test figures as well.
