  • Want to track when and for how long you dropped a buff via a timeline and event chart? You can do that.
  • Want to compare your action timeline against another of your own logs, or perhaps even compare each against their respective throughputs? You can do that.
  • Want to find the most salient points of difference between how you played and a fellow player in your party of the same spec played? You can do that, too.
