You are talking about "Class Reviews" back in Vanilla? I raided before the "Hunter Class Review" and I still never ran out of mana. The only way I can see one running OOM is raiding without mana pots which means one is a scrub and a bad raider.
I will bother to address the rest of your BS b/c I see the shit you throw caught on other clueless posters.
Vanilla class design was different than Retail. There were no "pointless" specs. There was one tree for levelling, one tree for PvP and one tree for Raiding.
Beast Mastery was the levelling spec, Survival was the PvP spec and Marksmanship was the Raiding spec. It is that simple. There were no redundant specs, just bad players who didn't understand class design.
So much for your BS.
