There are artifacts, and then there are these special items with special modifcations. We will still proberly see a real legendary like the ring or Warglaives, but OP really needs to wrap your head around these new gear grades.
I would not say that they are fucking the game up. They are changing it a lot, but they are also giving a lot more tools to players, so they can play a bit more with their classes and specs. All in all, we don't know what effect these items will have on the game yet. They might be so super rare, that they will have little impact on the raiding and mythic+ community. They might also be pretty common and easy to get, which will change raiding forever, since gear slots for curtain classes will be BiS from the very start of raiding.
Lets wait undtil the game launches before we give our judgement, but i do agree, that it is a risky move, that blizzard is taking.
Edit: And ofcourse, out of all the things, that might be wrong with Legion, these items are the least of our worries.
