"Engineers can now obtain the schematics for Lil' Smoky and the Pet Bombling from certain creatures found in Gnomeregan. Specialized Gnomish or Goblin engineers can obtain both schematics equally. The repeatable quest that used to randomly grant these schematics has been disabled."
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!
