Then the crying would be around mythic raiding being an "elitist activity that is, by nature, blocking their character's chances of doing dungeons" or some other bullshit response about mythic raiding requiring 30 hours a week (which is so far from the truth).
Regardless of the tool being used, it all comes down to them being bad at the game and having such poor communication and social skills that they cannot find a guild or group to play with. They just won't see it that way because they cannot be honest with themselves about their own skill level.
