DPS = Damage Per Second
This seems to be one of the few DPS parsers available with in-game command support. It should allow for in-game reporting as well, however I haven't quite figured that feature out yet. Granted, I also haven't done much with it yet either.
This of course requires you not to filter out any of the combat messages so the log will have all the information it needs. Unfortunately, AOC doesn't seem to support group-chat level filtering, so your logs may be showing other random people's damage contributions in each fight if you are too close to them. If anyone knows a solution to this that doesn't involve ganking or BO please let me know.
Once we get it figured out, it should be a great tool for determining what combat styles / feat / stances are working best, and where each class stands in terms of raw damage output.
