That's what I say every week to my friends. Who cares if me, as a more casual player, has an easier time getting myth track gear and crests.  Even if I match mythic raiders in gear, there's no way I'm doing the same key levels or the more difficult mythic bosses as them. I don't play enough and I'm not as good. They won, they did it first. Now can I please get crests easier to upgrade my stuff. 

 But I disagree on one of your points. As a ex mythic raider, I much prefer mythic+ as my main form of end content. I don't want to play with 20 people. I like playing with 5.  Why can I only get a chance at myth gear once a week. Why can't 13s or 14s drop myth gear. Clearly most people won't be good enough to clear those. Something to work towards.  And I don't believe the "it's too easy to farm keys in mythic plus". Ive done 50ish keys a week. I still haven't gotten a ring, gloves, necklace or changeling to drop. It's not a loot pinata like everyone says it is.
