Idk. What makes it 'impossible' IMHO is how more & more players developing tendencies to almost always 'copy other's homeworks' via either watching guides, reading strats on raidplan, or copypasting somebody's heal/mit plans. (Hilariously absurd to see people demand these in day 1-2 ngl). Deconditioning is a thing after all. Sooner or later you end up with more people who literally have no idea what to do unless they're spoonfed by ready informations. And worse, even expecting it.

Why do you think those guides/spreadsheets even exists from first place? To people who have recognized the general pattern by experience, it takes some stumbling here and there before they figure out what and/or how to solve XYZ. No they don't need to be 'ultra tryhard sweaty' either. At least not ex/savage.
