you referenced Wrath that just released, in 2022…
as i said OFC it was undertuned, as they released Wrath-Classic with the end game wrath patch.
as for 2008 Wrath, they made it that way as an entry raid, after the complaints they had about how difficult Sunwell was before it was Nerfed, i think only 1-2 guilds managed to kill pre nerf Mu’rtu
