Question is: Will they be available to every chapter fluff-wise or rather process creation? And why and how should I include them in my chapter and how will it change everything? I would really like to see some intriguing fluff behind them than bigger-better.
And they don't exactly look like primarch size/strength. So it is just about cloning ? To have endless amount of cloned marines instead of slow and risky recruitment process? W40k Clone Wars soon ?
