While it certainly can be a power creep, that is more so dependent on how they’re implemented in the game, and on the lore part, dependent on the individual Order and character.
Same way that both Grail Knight and Warrior Priests in Warhammer fantasy can be considered Power creep if we consider the table top and the lore, but if we instead consider the rpg, they’re barely power creep
And while they both started strong, and aren’t exactly weak rn, I don’t really think they’re the most power crept careers in VT2.
