LB glyph will be 4% more damage for your LBs... so it's definitely a consideration now. I run Healing Stream, Flame Shock and Flametongue weapon. I am really unsure what I will do with my glyphs, if to even touch them at all. I wanted to use the Lavaburst glyph for 10% more spellpower, but with it's cooldown I really wonder how much that affects your dps. Single target, 4 LvB will kill just about anyone in pvp, so I really dont need the overkill 10% more. I use healing stream as it makes healing with 4 elemental shamans and it reduces the healing they have to do in a boss fight.
