You can get max lvl heroic gear from just valor and rating you dont even have to time dungeons to get, You can get the second highest ilvl in the game for doing mythic+15s which apart from one or two weeks at the start of each season are pretty damn easy. In DF you'll be able to straight up craft 5 mythic ilvl pieces, so it's even easier to max out.
The issue with wow is the randomness of gear, not that no one has access to it.
