Game has always been about old players not giving credits to the rising youngsters, and youngsters not giving much respect to their oldest.
Just because you've been part of the people building up the competitive scene and contributing heavily to its success in the past doesn't mean you can freely shit-talk those who still want to prove themselves and somehow keep things going.
Just because you are a player who suddenly raised above the rest doesn't mean you have to behave like a cretin and disrespect those who do not currently have your skill level.
Make for a change, be the bigger man.
