Just wondering which sites people use for class guides and things of that nature (ie: Tankspot, Elitist jerks, Icy Veins, wowhead). Personally I used to go to EJ for class guides but once I discovered Icy Veins it was just so much more organized and to the point. Icy Veins is great for switching specs and getting straight to point of the playstyle, rotation, stat priorities, etc and is always kept up to date. EJ I find a little too convoluted and disorganized personally; it's great for theorycrafters but I'd still rather go to the advanced sections of the Icy Veins guides where they have already condensed all the math for you.
For encounters I used to go to Tankspot, but now I simply use the in-game dungeon journal and write down only the mechanics that pertain to me, and I might follow it up by heading to wowhead and reading the comments.
