Would you like an in-game parser?

[Sebazy]

Party composition has a very significant impact on your own dps. So if you want accuracy you need all the parties information not just a fraction of it

Precisely why I feel that if we are to get an in-game parser, it should be based around Potency per Second rather than DPS. It's gear agnostic and your party comp doesn't have such a significant impact on your performance that way.
