wowwiki , thottbot, wowhead are constantly tabbed up in firefox for me. Its been so long since I ran these places I forgot most of the encounters, and since I am mostly just running instances, I try to pick up the quests that I need since I am killing those guys anyway, its like free xp and cash and items to de for me. I will try to just run them first, I usually only do some research when I get stuck on something, usually another level solves most problems I run into.
