So much hyperbole in this thread.
If it is really a completely new player that has never played Legion, then that player should have to jump through hoops. We all had to do it. And to be honest by doing it, he/she can re-learn his/her class/spec anyway because let's face it, a LOT of things have changed.
If you did a couple of week's break or want to re-roll, you can insta-shoot yourself to AK 20 now, and 10 days or so later you're at max AK. From then, you'll do maybe 30-50 more m+ and the daily stuff and you'll be at 40 traits easily. First 2 legendaries, could almost be bought from a vendor, they're so common if you do the BLP-stuff. Then it only comes down to being lucky with those 2.
That is the only thing that people could theoretically be upset about, but again: with the recent changes to more legendaries, the gap between BIS and non-BIS for most classes/specs is really not that big any more.
