frost mages and sub rogues have a ton of CC, survive, and utility in those specs, while also having 2 other S+ tier specs to choose from. Arms does not have that luxury, so your point falls flat.
this is also just wrong
Aggrend said we’d be kings in Ulduar with the ilvl boost. It has been shown he was 100% wrong, so the entire premise has to change. It would make sense to leave warriors 35% below others in Naxx if they were 5% ahead of everyone in ICC. When the gap never closes, though, because we are on the ARmor Pen Nerfed patch, and a dev was ignorant of that, the point now fails.
