Make the fluff more compelling and reasonable, especially wherever there is a deficiency in internal logic (and don't put the onus of reskinning on the DM). Doesn't have to 100% perfect or anything, just better than what it is now. Start with Beguiling Strands, and work from there.Right, but how can they market to "former" players who haven't given it a try? It's kind of like going after new people but yet not because they already have ideas/tastes related to the product driectly where true newbies more likely don't.
The "metagamists" won't care or be turned off, because they focus on the metagame anyway.
The "ingamists", however, will appreciate the extra imaginative efforts, and possibly forgive or warm up to the overt metagame elements.
