It's also a bit strange that they are promoting themselves on some else's clan thread

What is a clan if not a space to meet likeminded people?I think it's great that there are different clans for different people. It's awesome that you can be a part of multiple groups too.Today I might feel like playing with fellow ladies,tomorrow I might want to play with fellow Aussies,the next day,who knows?But there's always a space for me to start a fireteam with whoever I feel like playing with.
