I don't need a parser to find out who is doing awful dmg, I check which class, then I check their gear, I don't need a program to tell me information I can already find.

Did I join a group with a bard or nin? then dmg is going to be low automatically, there is certain flags that go off, drg not keeping up heavy thrust, nin not using dots or keeping up huton, I can tell who is doing terrible just by looking at what they are doing in general / what class / what gear they are using.
