FFXIV arena definitely needed a matchmaking system, but it should have done something similar to other MMOs... When a person with a high or low rank queues up, the game searches for people with similar ranks to match them with. However, if none of those ranks are available after a certain period in the queue, it will widen the parameters to eventually include ALL players queuing. So, basically, if people around your rank are queuing, it will force you to play against them... but if not, you will eventually get to play. A rank 30 person won't be waiting 1000+ minutes for a queue...
