Here's a quick run down of how: You have a bunch of skins and stuff, right? Okay, take those skins, and now add requirements to unlock them. You want a special DMR skin? You have to get ten headshot kills, or twenty, or X number. You want a shotgun skin? Twenty one-shot shotgun kills. Or even better, make it tied to playing objectives. Hold the ball for a total of 100 seconds. Hold the hill for a total of 200 seconds. Capture 5 flags.

Seriously, that was off the top of my head. If I can do that, surely the dev team could have done that too, but no, they want to go and make everything a trading card game. Maybe I don't have the time or patience for that shit, and I just want to play my fucking game. This is EA-level bullshit.
