>Requires two AA batteries and not a rechargable battery pack
Not sure what is your point...
I prefer batteries than rechargeable by far, so it is a matter of preference not "being" elite or not.
And people can get the rechargeable kit if they want to; they have the choice (which is the best of the 2 worlds at the end for a lot of people that already have a set of rechargeable batteries).
The controller is absoluttly fantastic. Been using it with Halo 5 for a week now and it is really an awesome piece of hardware. The Xbox One is already an amazing controller but the Elite controller is just perfect to me. It feels really good.
