I've got a question about Glyphs. Since I'm still gearing up for ToCr, I still deal with AoE tanking in heroics, as well as in VoA. I've found Glyph of Disease to be a pretty useful glyph (also considering Blood Strike's low damage, since I 2-H tank) for refreshing Diseases, and was wondering if anyone has experimented with it. The Frost Strike Glyph is an obvious choice, but I'm wondering what people feel about Glyph of Unbreakable Armour vs. Glyph of Obliterate. While Oblit. is obviously a great threat move, I'm wondering if the 20% added by Glyph of UA is additive or multiplicative (could be extremely awesome if it is). Thank you for whatever help you can give. I also apologize if this is more of a simple question, but I think it does have some merit, due to the lack of updates in the original post.
