[Feat] Work Smarter, Not Harder

[Silva Stormrage]

... This feels oddly targeted towards players who use flaws. Mostly flaws minimally impact builds. Vulnerable is -1 AC and isn't incredibly relevant to most builds as a 5% more chance of being hit is pretty minimal.

Do you just hate flaws or is there some joke I am missing here? Flaws aren't even unofficial, they are just a variant rule and its up to the DM to allow or disallow them.
