We've recently looked at builds for protection and retribution, so let's continue that trend and take a look at glyphs. I'm going to review all of them, as we're getting pretty close to Cataclysm, and I'm going to also review them in a more global context instead of talking about what is going to help you on hard-mode Lich King.
The way I've set it up is that everything that you're likely going to want without question has an asterisk next to it; those are pretty much things you'll want to take. If you look through the major and minor glyphs, you'll notice that there aren't very many marked as such. There's a reason for that. We just don't have that many spectacular glyphs that are useful in all situations for those types. That's not to say the other glyphs are bad (well, some are, but we'll get to that), but they're more situational and require some choice on your part.
