As it stands... only thing that non-casters stand to gain is the ability to sell glyphs and the shoulder enchants (and those aren't really that great compared to BS/JC for tanks).
With the loss of the 3rd major glyph (as far as I know it's still unconfirmed). Is it worth taking inscriptions on anything but an alt?
I haven't been on the Beta in a while, so sorry if this is outdated. :-)
