On a good note, I seemed to have totally missed that Marks of Honor were going to be on the Currency tab in the character screen instead of taking up precious bag space until i actually logged in yesterday. Yay more bag space!
My favorite surprise in Echoes of Doom, however, was discovering that my Herbalist now has a new self-heal over time spell: Lifeblood. It's instant cast and has a 3 minute cooldown. There it was just sitting in my General Skills. A guildie had to point it out to me. I should probably take a closer look at the patch notes.
What changes did you not expect to find in Patch 3.0.2?
