Haven't seen a post on this yet, but i think its a pretty big change
Glyph of Lava Lash - now Increases the damage dealt by your Lava Lash ability by 20% and no longer requires your weapon to be enchanted with Flametongue.
Speculation!!
Now if I'm reading this right, Lava Lash will no longer need flametounge enchanted to do extra damage? That means we would be able to enchant our offhand with windfury again, or even frostbrand and still have a full power lava lash! Although now that i think about it, we might still very much prefer Flametounge for the fire damage it does.
What do you guys think?
