I literally never said that you couldn't play her that way; I said that your choice to play her that way shouldn't have any bearing on discussing this skill in the playtest packet, because it's your personal choice to be that militant about a thing that you're not required to be that militant about. If you're going to take that as dismissive of your choice, then that's on you, and I'm not going to apologize for that.
ETA: I've also asked you specifically what is barring other Sylvanborn from taking this skill, or why other Races couldn't use it around Sylvanborn, and you have yet to give any answer at all; looking at your OP, that seems to be your major problem with this skill, but you haven't actually explained why it's a problem for anyone else. I'm genuinely not trying to be a jerk here, but if your problem with the skill boils down to "I don't get to use it because of a character choice I've made", then that isn't a problem with the skill, and it's not even a problem with your choice, but a necessary consequence of you making that choice, just like people who choose to play Biata have the consequence of no Celestial magic, and people who play Dryads have the consequence of no metal weapons.
We've all made choices, and some of those choices in 2.0 are going to lead to things we may not like, but unless it presents a glaring problem with the rules and skills, those personal choices aren't grounds for change.
