I'm curious as to what this is going to do to airbending and the air nomad culture.
Before, all airbenders were air nomad monks with a very specific lifestyle (vegetarian, peaceful, spiritual etc.) and to our knowledge there weren't any "average joe" airbenders, people who could airbend but didn't conform to this lifestyle. In my mind, this kind of set airbending apart from the other elements. Also, they were a race that was composed of 100% benders.
Now we have a bunch of random people who are gifted with airbending and it seems that the majority of them have no interest in partaking in the air nomad lifestyle. These new "average joe" airbenders also have the possibility of passing on their bending ability to their children, who will also have the choice in whether or not they want to partake in the air nomad lifestyle.
On one hand, it knocks air bending down and puts on the same level as the other 3 elements. On the other hand I find the idea of having a bunch of airbenders who are normal everyday people instead of monks interesting. Especially if this carries over into another potential sequel series with an earthbending avatar.
