I thought InArt killed it with the faux-rooted hair. I didn't expect it to be what it was and found myself glad that I took the gamble on it over the sculpted hair. I'm also glad and hopeful that they use the same technique for other figures, like Aragorn which will completely smash if it's this kind of treatment.
I just don't think this "trend" of rooted – if there really is a trend at all – needs to happen. Keep the faux-rooted to special extremely high-end projects and leave the rest to sculpted. I don't agree that the old method is outdated, because it's actually a standard method that many figure makers will still use. It's there because it works within a certain cost structure. Most average figures can't afford to be priced in a rooted hair category of InArt's calibre, so for under $300 we had figures like Baby Doll, Selina, Wonder Woman, Gamora, Black Widow and Scarlet Witch all suffering from mass-production consumer-grade rooted methods rather than the art that InArt produced. You've probably noticed that most of the new versions of the characters/figures I mentioned are now being done as sculpted hair. Hot Toys seemed to understand where they failed. I just got the new WandaVision Scarlet Witch and the sculpted hair on it is so much better than what they did with previous versions. It's not perfect, but it left nothing more to be desired that rooted could beat.
