I feel like I have a dinosaur opinion but here goes.
SOME special characters/epic heroes are alright if they aren't unique, like the Swarmlord got an excuse for showing up in a number of places. Or the avatar, even though the craftworld should REALLY not want to bring it out often, there's at least a present for it showing up for every craftworld. Pic related is mine themed for my Ghost house.
You make your own version of a character, great! Use the profile, no problem, I use to use old metal Celestine as my /Yourdudes/ saint back in the Witch hunter days.
I feel that the established special characters makes the setting smaller imho. Both in terms of size and renown. Every battlefield should not warrant the attention of a Primarch, or the Silent King.
I still recall a game I played AGES ago in 5th where Kharn, the only special character on a whole apocalypse board, showed up in his landraider, and got sniped by a squad of Nob bikers with a Klaw, all that reputation, get ganked by a random chucklefuck orc with a power tool. While hilarious, it kind of makes the legends of the setting, like Kharn, seem a bit lackluster.
