Ok, first I want to throw out a reminder about sharing opinions on glyphs. Everyone has personal favorite - I include myself in this pool of guilt. Right now I'm sporting Glyph of Healing Touch, which most Resto Druids don't use. I like having a fast, powerful heal and Glyphed HT has half the cast time and almost double the healing power of Nourish. It's not listed on most Druid sites, so I left it off the list because I can't back it up with expert opinion. My point is... I'm suffering too!
So in the interest of not confusing the befuddled, let's hold back on tossing out too many suggestions. The goal here is to create a list of solid, well-established glyphs. Crafters want to know what will sell and by following standard builds and accepted glyphing practices we can provide that information. I'm not going to stop you guys from disagreeing in the comments, but I will point out that debating the merits of a glyph is more likely to get it passed over when Scribes are choosing which items are guaranteed to sell.
That said, let's move on to the remaining classes in our Glyph suggestion list:
If you don't see your favorite listed here, it's because I didn't find a reasonable level of agreement on it and left it out. That's also why some lists are skimpier than others. There were many cases where an EJ thread proclaimed a glyph "situational" or "too close to call" and other sites were split on it, so I didn't list it. There's still plenty of debate on class mechanics and that will surely be reinvigorated by the new 3.1 glyphs. Hopefully this list is narrowed down to the sure bets in terms of sales value.
As for minor glyphs, I leave that up to individual crafters to decide whether they want to venture down that road. I think minors will be more volatile in general, but there could be some classes where it's very obvious which ones are good and which are crap. You don't need me to advise in situations where the choice is obvious, and I'd rather stay out of the debate for situations where it's not. Here is my suggestion: if you know a minor is valuable then make it, otherwise skip them.
I hope these lists are of use to our Scribes out there, that's my primary intent. Feel free to disregard any class puffery that may develop in the comments. If you're worried about a particular glyph then just don't make it. You should also use your own personal experience to expand this list, these are just suggestions for classes you may not know much about. There are plenty of glyphs to go around, so you could easily restrict yourself to four or five classes and still have a wide selection to sell on patch day. Good Luck!
