This is still BETA - as in *not done yet* - stop freaking out. Most likely these are either minor glyphs or low level ones you don't need to be level 80 for.
And as for the Ret mana nerf - if it is a big deal - then they will fix it. Most of the time the data for these builds are taken in the middle of them changing things - so they could already have solved this problem - just wasn't in this build.
Again - this is BETA people - if you have been following the changes at all so far you know that a lot of stuff has changed - and very quickly - so don't fret yet.
