After grinding the Mountain Top quest line for not even that long, I found an issue with the 2nd quest step. In this step, you have to complete the triumph titled "In Pursuit of Honor". One the parts of this triumph is to get double kills, but it HAS to be with gernade launchers. If you do them in comp, then you need 40 double kills. While trying very hard to earn these double kills, i only managed to get 1 in the span of several hours grinding. You can only reasonably get them with heavy, even then its no easy feat. It doesn't really matter if you do it in qp or comp, it's incredibly rare it'll happen. I really think that part of the triumph needs to be changed, say to make it just generic double kills. It'll take way too long otherwise, and I guarentee that people will cheese it in order to do it by messaging the other team and arranging to let each other get the double kills, instead of playing the actual game.
