People really should follow their own advice. You didn't even take the time to edit you post before submitting it. I know that this isn't an English course, but seriously, "write"?
The problem with the majority of recipe ranks that are currently posted is that the information was pulled from the lodestone. The lodestone gave a range of ranks for the recipes posted there, instead of just the rank of the recipe. Most sites just used the low end of the range as a ballpark figure to give people an idea instead of just leaving the field blank. The problem with reporting corrected recipe ranks, is that there are multiple things that could be reported. Some people will submit the minimum level to attempt the synthesis, some will submit the rank they were first successful at the synthesis. Without the recipe actually telling us what rank it is, it is difficult to find the exact rank of each recipe. There are people who are diligently working to find these ranks and post the corrections, but an endeavor such as that takes time. It is in the community's best interest to have at least a close, ball-park, figure listed in the rank field for each recipe than nothing at all.
