I kind of always chuckle whenever I see anything related to "#1 this/that based off FFXIV logs". That site and it's info will never be 100% correct simply due to the fact that not everyone uses it. So the "#1 Ninja in EU" could quite possibly actually be #20 in EU. Nobody ever factors in the possibility that people who don't use parsers could be better.
Now for topic wise. This isn't a bad idea. Helpful information is always nice.
