130 Specialize Evocation No Mana Reduction?

[lurk]

I'm 100% that specialization should go off every time. The reason I know this is because the AA SCM said it increased chance for spec to go off. In that era there was a ton of parses done to show that specialization works everytime and SCM simply increased the % mana saved. I don't have time to look this stuff up right now but there has to be Luclin/PoP era posts explaining what specialization does and what SCM does...not classic but then I seriously doubt anyone actually put in the effort to test this before SCM.
50 spec should be 2.5% mana off.
200 spec should be 10% mana off.
SCM3 should be 20% mana off.
