Maybe some hardcore players don't see problem, but for most other people same MSV was far beyond terrible, because dogs were like Netherspite (Karazhan's second to last boss, skipped by many raids) on steroids, Feng was on par with Archimonde, etc. with tight enrage timer on each boss, with raids having zero exploration element.
Mistake occured with Ulduar' hardmodes which later x-muted into heroic modes, which led to rise of so-called hardcore people and steady decline in raiding population due to overtuned normals (greatly evident for t11 and t14). Raids never were as tedious and with such abuse of arcade elements as they are now. Ofc many guilds are disbanding because recruitment pool becomes smaller and smaller, as normal raiding exists no more. And without proper normal raiding - there won't be proper recruits for hc guilds.
