I'm assuming the lie you're talking about is that "casuals" pay for the game which is more and more proving false. Sure in Vanilla that might have been true, but that's because the majority didn't even do any raids at all because leveling and gearing were time consuming.
Now that there's sponsors and things like that as well as esports stuff, the average mythic raider or top end pvper pulls in more revenue for Blizzard than a massive number of "casuals." Whole guilds doing race/faction swap? Yeah let's see casual guilds doing that. Whole guilds where each member has 2-5 accounts? Not "casual" guilds.

It shouldn't be that easy. As usual it's a spit in the face of players who actually work for things. The same way that you can just wait 2 expansions and blow through blindfolded and get the same rewards. We need to stop rewarding incompetence. It's not a desirable trait. If their life is that bad that they need that ego boost of killing a boss in LFR difficulty the way it is, they need to seek professional help.
