There have been funny little things like that on armor since day one... I think Bungie did a very good job building rivalries/ personalities into the game experience... It is incredible that they pulled it off , the way they did. And it is amazingly simple... People that started with Hunters saw all the quotes bashing Warlocks... Warlocks saw quotes about Hunters... Titans saw quotes about Titans... things like ' I didn't get hit, I body checked a rocket' '<ladies name> went into the darkness alone, then i heard the most terrifying sound, she was laughing' ' No ammo?... No problem" ... That's why titans just walk around with puffed out chests and avoid the rivalry all together... I rambled a bit, i studied psychology and find this whole thing absolutely amazing...
