Nope.
They lose one skill.
No. They lose two skills. The elven racial can't be assumed to be useful since it can't pick any skill and perception is easily taken as part of background or class. Getting perception twice doesn't do anything. Plus, what if I don't want perception at all. Currently I can do that with half-elves and have my two skills. If we do your thing I'm forced to select perception, costing me a skill that I'd rather have as something different.
And no identity at all. Either they go with Elf parent and are a very elfy half elf. Or they go with a human parent and become more unique.
Or they go with a mix and are...........................a half-elf regardless of where they are. I mean, you've never played a half-elf as a half-elf? You play them as elves or humans? What's the point of even picking it as a race if you aren't going to roleplay it as what it is?
Why should every single mixed heritage character be identical? That's not how it works when you have mixed heritage.
Er, that's what they are doing now. Every last one of them is either full elf or full human. And NONE of them is a half-elf, since genetics don't work that way. You don't get to mix species, end up looking genetically different but being 100% identical to a single parent. What they are going with is worse than giving them all a single, but at least half-elven identity.
Your argument there is basically, "Well, right now it's somewhat off with regard to genetics, so let's just toss out the baby with the bath water and not give a fig!!!"
Calling it a "feat tax" when your first level feat is limited anyway doesn't make it so.
It's factually so. I can have a race and pick a 1st level feat, or I can be taxed that feat and be forced to use it in order to be a half-elf. If you are being forced to use it to be a race when someone else can be a race AND have a 1st level feat, you are being taxed your 1st level feat.
