I support the use of a recount type of device in game. As OP said, it's not just to record DPS, it shows who's top healing, who's interrupting, who's taking the most damage and so on. But just from a purely DPS recording device, it helps raid leaders know who is doing the highest and lowest DPS and match that to how good or bad their gear is. Having reasonable DPS is important and only casuals would argue against it because they want to make their own spec and have fun but, unfortunately, making your own wierd *** spec to have fun isn't going to progress a raid that needs a DPS to be all it can be.
