Why are you all in another players profile worrying about what they are doing ? Why do you feel that its so important to question the how of their advancement ? Now if you are vetting them for club membership its understandable . But if its just nit picking and fault finding then its best to leave it alone .
If its not taking anything from you as far as playing the game and having fun then leave it alone . One of the best rules to live by is : If you spend 6 months of the year handling your business , and the other 6 months minding your business . Then you will have very little time to be in other peoples business .
