Well if we implement this we can have a reduction of people making a fail report and force them to fill out this form. For example: http://forum.randomgs.com/index.php/topic,12614.0.html
And this is a bit more tidier imo. It's not gonna hurt us either.
True, BUT it also removes the user input not just from the one reporting, but from others who were there, the one being reported, etc - that is not IMO good.
With this system, it seems like
THIS report for example would have been approved since you'd only have the evidence the reportee presented, and not get the input from those who pointed out how what happened there wasn't against the rules, the more technical aspects of what happened, etc.
I like the idea of streamlining the process, but if it doesn't give a chance for the accused to reply, for that person - and those who play with him or her - to reply, explain, give counterevidence, then I don't think I'd want it replacing anything.
