This is something that you do with a skill and attention to detail that constantly has me dumbfounded in all honesty.
Thank you? I'm always trying to find options that can make my army a bit more effective than what was already offered. I feel like Necrons can do a far superior job being Rubrics than Thousand sons can, even without access to psykers. And don't get me started on using Loyalist Marines. I'll do whatever I can to play an army the way they SHOULD be represented. Now how GW forces them to underperform.
I suppose I can understand the die hard desire to run a single codex to the exclusion of trying to work it out better in other fashions. And I would totally get that *IF* these people were playing it in order to run, say, Deathwing. Ravenwing. Hell, even Centurions. But with the DA codex coming out, I think GW did the worst thing it could ever do:
Repeat the same army twice.
The Demi Company for DA and Vanilla are basically identical. So now the bonuses are the same too, and you KNOW you'll find people running it just for the Double-D (yeah, I said it) razor spam. Why bother? Play DA for what you want. A deviant chapter, NOT running the same boring stuff.
I'd rather see BA not get the demi, so they can have something uniquely suited to their strengths.
