On the contrary, I think it takes a special kind of actor to be able to emote and create a likeable character while we never see their face. That's what makes voice acting, to me at least, so impressive- creating characters and conveying emotions with only your voice. As others have said, Star Wars definitely has a "looks cool, but does nothing" problem. With the Armorer, at least they've given her just enough character and mystery to be interesting outside of her looks. I'll always maintain that Phasma should've been TR-8R/FN-2199, the Stormtrooper that Finn fights on Takodana, rather than just some random trooper. Would've added more weight to their fight in TLJ, but alas, she was wasted. That's kinda what Marrok amounted to as well, even if he fits into the overall theme/plan of resurrecting the dead (assuming that's what he was and not just a weaponized fart cloud). Fingers crossed that Enoch will at least have a single cool, meaningful moment before he goes out.
