"I'm more upset how these clans which stand 2nd or 3rd but only having 50 cp would also get rewarded towards war cry gear. I thought diamond was an elite class, but I am wrong."
Bro, I hear what you are saying, but why would you worry about that? It's just SWAG. End of the day, it means nothing. Speaking for myself, i'm not going to lose any sleep if some opponent's player model has the most recent 'war cry' helmet. It's not like i even see that when playing.
Ultimately, what determines the Elite level of your clan, ...is it's ability to win. How it plays. Who it beats and how good of a fight it puts up. It's not what color of helmet your player model has.
