Previously the only 'roadblocks' was the amount of time you were willing to grind certain dungeons for certain pieces + farm raids with a geared guild.
Now you have artificial roadblocks such as AP (time-gated) and Legendaries (luck + time gated). GL trying to do Krosus as a DH without Ring or Shoulders.
Nobody is saying you should be able to run Mythics within 1 week. But artificial time-gating is stupid and serves no point.
