Seems like this achievement is only given to those who are popular, specifically regarding the forums, i know plenty of people who help a ton in-game and recive only the recognition that those they helped give. But i suppose that's just my opinion...
its true that there are many helpful people around, but, recognizing all the useful people isn't practical, so, the devs have chosen to recognize what they consider to be the MOST helpful, or the BEST of the crop. These are players who are models for others. If you think that there are others who should be recognized, by all means, drop their names on my VK thread, where they will be reviewed. More valiant knights will be Comming. These players are not the last two.
