Since these are the only two toons I have really glyphed, I am gonna go over which ones I currently have on these toons.
Glyph of Blocking: This one is hot. Every time that you block, your shield block value increases by 10 percent. This is a must have for prot Warriors.
Glyph of Revenge: Glyph of Revenge is another one of those must have tanking glyphs. Every time that you use Revenge, your next Heroic strike is free. This is a big threat booster, and since you should basically be spamming HS on bosses at this point, you get to spam even more HS. I got a feva, and the only cure, is more Heroic Strike Spam.
Glyph of Sunder Armor: The third gyph is a litte bit more iffy. This Glyph sunders another nearby target. This ability is obviously more for trash, which is why I will probably be switching to Glyph of Devastate. This Glyph puts two sunders up on a mob per devastate. Very nice for boss fights as you only need to devastate 3 times for a full stack.
I cant think of all of my minor glyphs atm, but the one that I KNOW I have is:
Glyph of Thunderclap: Increases the range of Thunderclap. This is very nice for multi mob tanking.
Resto Druid Glyphs:
Glyph of Regrowth: A very nice Glyph that increases the amount healed by your Regrowth by 20 percent when you already have the Regrowth Hot rolling on whoever you heal. I would say this is pretty much a must.
Glyph of Swiftmend: Absolutely required and quite amazing. When you use you Swiftmend, it does not consume the hots. I repeat, IT DOES NOT CONSUME THE HOTS. This make healing even easier and is essential for any resto druid.
I am only level 73, so I have not gotten my third major glyph yet. When I do, it will be either:
Glyph of Lifebloom: This makes the Lifebloom roll longer before it ASPLODES.
Glyph of Innervate: Basically, for what it looks like, when you cast Innervate on somebody else, you get the innervate effect as well. This will be wonderful for longer fights and if you are having trouble with mana.
My minor glyphs atm are Glyph of Rebirth: No reagent for my battle rez, Glyph of the Wild (think that is what it is called): Reduces the mana cost of Mark of the Wild etc, and Glyph of Thorns: Really not great, but 1 hours thorns in nice when leveling and questing.
