Depends on what content you're applying this system. I mean, to me, it just feels like a really overblown parser and I don't have problems with those either when they're applied in the appropriate content. For me, that content would be expert, savage raids and ex trials.

Now, to implement this system would also mean to change the way the game works as well. After all, its far easier to complete expert content when an entire group is decked out in 340's than one with entry lvl gear. So that system's algorithm would have to match the party's overall ilvl to provide fair grading. After all, it would not make sense for example, to give a SAM in i300 a lower score because he could not match up a RDM in i340, even though the latter's pumping out half of his skillset and dps and still providing "good" results.

Then there's 24man raids. I will not go over that cuz people have already gone over why this can't work.

So all in all, while the idea sounds...ok on paper, it just sounds like an extreme solution to what could be simplified if a parser existed for the high end duties.

Besides, if one person in the party is holding the entire group back, chances are its a PF pug group and the greater solution is to kick the person out.
