I remember those bits from Index Astartes, too ... I guess the BL writers just didn't pull off the HH as I would have expected based on those other sources. Just a question of different interpretations. If they had made it more gritty rather than pulling off all this Immortal Perpetual Superman stuff, my perception might have been more positive! As for the licensing bits, some of them are actually pretty decent deals, but others are watering down the IP and kind of taint it with lackluster quality. Already it generated quite a bit of ridicule: http://www.pointandclickbait.com/2016/05/i-for-one-welcome-our-new-pigeon-overlords/ FWIW, I cannot see the logic behind Custodes as an army either. Rule of cool (popularity) trumped setting logic there, so maybe GW thinks they could just replicate the effect with another new product line that comes across as even more heroic and superior. It certainly seems to have worked well for them so far.
