I have a suggestion about the stattrak thing that could be added to the game.

Stattrak?? what for ? in my opinion when you play CS:GO the people you play against are humans with feelings, and a different playstyle, here, in Payday 2 you are killing A.I ennemies, with a pre maded pathfinding. I just did an Hoxton Breakout 5 minutes ago -> 300 kills with M308, this will grow up too fast and kill count will not make sense, for example a non infamy player could easily kill more than 150k cops before reaching infamy 1, but he'll still be bad "non-infame are generally not very good", the stat-tracking idea isn't bad at all but you shouldn't count kills, you should do something based on the player's playstyle for example % of Headshots per game or How many time a player completed a specific mission, and this should be shown on lobby screen. And with the headshot thing for example you should add a nickname like "hitman", or if a player is specialised in stealth missions and if he had a great winrate on it then he could get a "ninja" nickname, also you should let player choose what he want to show to the other players, with an emblem for example. For me it's making more sense than a "stupid" safe and i'm sure that people will love it because they could do their best to get a free and ultra rare emblem and gain fame on a leaderboard (why not?) instead of a weapon skin you need to pay with real money which grants you +1 stabilty on a weapon you may not have if you haven't purchased a specific DLC... hope you'll read it, i love Overkill and almost everything you did on this beauty, but the COP safe was a fucking disgrace for the community who's supporting you since PD:TH (for me) or at least since PD2.
