3) Gear from 85 to 90 doesn't leave you in a position to go to heroics, even if you get all the gear available.
This is not accurate. The "Heroic" dungeons are basically the entry-level lvl90 dungeons. You do not need specific item levels to queue for them or complete them.
I think that you are thinking of the Challenge Mode dungeons which are designed to be very difficult and so you probably will not have adequate gear for them when you first hit 90.
So, no, it's something that was referenced years ago and that they finally expounded upon within WoW.
The low level players never want or need any help because it's too easy. I don't want to spend a lot of time learning each boss's tricks and having to run back countless times.
So the game is too easy but you don't want to put in work to learn a boss's fight?
Please make up your mind if you want a hard game or an easy game.
Basically they're Apple adverts, basically.
