Chaotic is midcore, in case you were wondering

[Xrono_Amber]

Let me ask you this, do you consider Strayborough first boss to be that? Because you just exactly asked for Strayborough difficulty. But good luck trying to convince most players "look guys, strayborough is a midcore content". And ive seen wipes to that boss where they have to reset.

My hot-take is that when people ask for more "midcore" content, they essentially want dungeon-bosses from Dawntrail, but made separately from said dungeons so it would "feel" cooler.
And they want this said feeling because of this:

Sure, but Alliance Raids are braindead...

Because of the reputation of casual content as "braindead". Is it easy? Yes, of course, that's the whole point of it.
But because of such evaluation it doesn't feel cool to say "I've cleared it!" And "midcore" is the desire to have something to brag about without the ability to invest much time in one instance or having some great gaming skills.
