i'd say keep the rating system if it wasn't obvious people generally aren't rated up or down by the content of their post, but more due to their "popularity".
Right now rate up/rate down system is almost completely pointless to follow because of the above reason. If people don't like you here for whatever reason your ratings will almost always be negative, regardless if the information you're saying is correct.
This is misleading to people who browse FFXIAH forums and may not know that this kind of thing goes on, They may look at a posts ratings and assume what the person said is wrong, when in fact the person saying it could have been right, maybe he said it in a douche-way, but then we got even just 1 person whos going to be mislead by this system.
Basically it does need to go, Maybe keep the Rating system for Items/etc, But it needs to be removed for Forums/ personal Pages. It really serves no purpose there.
