I'd do that, but that doesn't sound like fun at all and since I'm not really in a hurry to get the Ace23, I probably won't do it. That being said, I'm definitely going to do that for the ammo ribbons, because the LMG unlock needs 50 of those, and I'm at like 3/50 after hours and hours of playing support.
I'm sure this will be an unpopular opinion, but there's something I enjoy about playing metro/locker that is almost stress-relieving after work. It's just a permanent "AHHHHHHHHHHHHHHHHHHHHHHHHHH" the whole time....it's kind of nice sometimes!
