Achievement Ranking System

Hello everyone. Was thinking recently on what FFXIV would be like if it had an achievement ranking system. An example would be bronze through platinum trophy with the sum of achievement points deciding the rank and adding an interface icon to display it next to player name. In the past I have played other mmos that have implemented this concept and found it to be a fun way to get a general view of accomplishment. There are obviously down sides to the idea, but what are your thoughts on it?

Can you describe this system?

Aside from the occasional title and item, achievements are not that much of a big thing in FFXIV...
