I'm convinced most people are terrible at this game.
I think the lack of skill based match making makes the bar seem lower than most games, for those who are above average.
This is about as easy as when I remember playing games like Resistance, Starhawk, Killzone and MAG. Those games never featured any sort of skill based filtering and my KDR always sat between 3 and 4.
Feels quite similar here. Not that I have a problem with it. I like to test my skill within a random sample, see how I perform across the whole distribution. Everyone being forced into an average game every time isn't much fun. At least if you are bad here you have the potential to get better, become better than average, but with skill based matchmaking you are always just average, unless you manage to become an extreme outlier.
I'm definetly one of those people. I'm like lvl 15 and still feel like I have no idea what's going on. All I do is run run run die, respawn run run die, respawn die. I have some games where I do well, but most of the time I feel like I don't even know what killed me and it's just a coin flip on wether I run up on someone unsuspecting or they run up on me.
I'm normally not bad at video games.
This is the other side of the same spectrum, perhaps? In other games skill based matchmaking will make you seem better than you are. If you aren't all that great at these types of games, then you will find yourself against equally low-skill opponents, that's true in most popular shooters like Overwatch, Call of Duty and Destiny.
