Lol.. I just think it's pointless. You establish what class everyone is in the lobby. If you join an existing game, you only have to press start to see the classes you're playing with. Did we really need a constant reminder of which role everyone is?!
But it's given me an additional 7-8k kills, and I have no way killed that many in Chaos. I have played a maximum of 10 games total, with under 100 kills per game. Which is no more than 1,000 kills total in Chaos.
In Ghost PC updates - section, a brief summary is there for your convenience which happened a couple of days ago now, As well as PS4 & XBONE sections - have all had an update with the gamertag & class.
