I personally don't see anything wrong with a tool that measures how much damage you're doing. I too used ACT for your same reason - to optimize my rotation and to see what skills are priority. It also did a few other things for our guild, too: - Initiated race/class discussion - Promoted more in-depth learning and theorizing about your class (and encounters) - Made us a better guild. Sounds silly, but the people who look at damage meters as a self-improvement and educational tool and were smart enough to figure it out, ended up doing a whole lot better in encounters. If everyone does better: the guild does better. I'm speaking in terms of classes who focus on damage. BUT it allowed tanks and healers to get some data on their classes, too. It boils down to the person. The people who are a little deeper into their hobby re-tool and rework their strategies, gear, specialization, and rotation to achieve something better. Those that just want to whip it out and measure it up against somebody elses can do that on their own time. Just disable a reporting button. That's what seems to turn people off, idiots spamming damage meters. PLEASE NOTE that this game will NEED a comprehensive breakdown and parsing of all events during combat. Not just dps = total damage / encounter length and all the mouthbreathers rejoice. Take ACT for an example.
