A feat is a feature not an ability. Stat blocks literally have their own section specifically for feats. Racial bonus feats are a feature of racial traits. Alternate Form, and by extension Wild Shape, does not give you racial traits.Originally Posted by PHB, pg 87
I would even argue that even Alter Self would not let you get the human bonus feat. It's not even given a designation.
The extra feat is literally "1 extra feat at 1st level." As you aren't first level, it would be impossible to benefit from this trait. Compare it to elves:Originally Posted by PHB, pg 13
The human trait is an extra feat at first level. The elven trait is proficiency which gives bonus feats. One is a trait while the other is a feature of a trait.Originally Posted by PHB, pg 16
