It's because that thread exists shows a huge interest in a match making system. They didn't have to make a world Party finder, after all the forums exist.
The point of it all, the match making, the party finder, the raid finder etc, is for convenience for a service that has a pretty high demand.
I could say the same thing about Lord of Vermilion and some of the holiday events. Yet. I understand not everything implemented in the game is solely just for me alone. I would agree with your point if I was the only one interested in such a system. However. . . . As the reason stated above, there is interest.
Can you explain to me what you mean by this? Sorry I'm not following. I need further clarification.
Instead of organizing players who are interested in this, you'd rather have us continue to use the Party Finder, cluttering it up with even more ads you prolly aren't interested in or even want to see. To me it sounds like you don't mind players doing anything in regards to match making or finding an eternal bond. It's just you're not comfortable with SE dedicating the time to make a system to better the many voices who may like this.
But match making does take time. You don't just "Oh lets get married because the system paired us". Of course not. This is a way to bring together two people with the same interests. If they don't like each other, tough. They can move on and find another. If they like each other but they aren't interested in doing an EB. Fine. They just received a new friend.
Not everybody does the approach you would like others to do. Even with the marriage partner thread, I bet you there are A LOT of players who aren't comfortable posting on it. This gives them a way to step outside of their comfort levels.
I mean you're free to disagree with me. It doesn't mean I'm gonna bite your head off. Just prepare yourself for a debate. Bwahahahahahahaha
