Would you like an in-game parser?

[Reynhart]

Most content only needs 1 healer 90% of the time. If he was DPSing while I was healing, I'd be fine with that. If he was standing around doing nothing, I'd say he wasn't doing his job so I'd start DPSing myself to try and make him do some work.

And the same in fights like A1S, what would you say ?

You just proved my point. You just really did without realizing it.

And you proved mine. You would have parsed on that fight, and called out the DPS for being lazy or slacking, even though they won the fight. You shouldn't, they did enough.

I've seen farm parties messing with their DPS too sometimes, because mistakes happen. I've also seen farm parties screw mechanics they have dealt with dozens of time before, or just making a wrong decision, because mistakes happen.

Besides, a parser does not tell you what you did wrong, it only tells you that you did. If you don't bring a solution, then calling for the problem doesn't help.

If however they used some mitigation skills, DPSed, were removing debuffs and generally contributing to the fight without standing there looking pretty then no, they did not fail.

Does a parser tell you that ? Does a parser tell you how many damage the DPS dodged ? Or how he ran around the arena to help someone on a add or to freeze a tornado because no ranged DPS bothered to do so ? Or how many DPS a SMN lost by raising several people in a row ? Or if the PLD needed some MP back so he kept using Riot Blade for several seconds ?
