12 years ago an astute commentor noted that Warhammer lore was far less static than some would like to believe.
I stumbled on this comment while looking for something completely unrelated to the boring Primarchs but here we are. Also Leman Russ' original version was almost as ugly as the modern incarnations!
That's because he's not even a primarch at this point - just an Imperial Commander.
All the people whining about 40k's "static, unchanging" fluff need to take a long had look at just how much has changed over 20 odd years.
