I also have 1 bar this year, but no lag. I rarely ever lag honestly. Have you checked your router settings? Enabled UPNP for one if it's not. This should open your NAT. You can also forward ports. Try running a speedtest when you're lagging. You can do this at www.speedtest.net. If you're getting a really low download rate then that's a good sign there's an issue with your internet. From there you should be able to diagnose the problem with your internet provider.
Not saying the issue solely is on your end, but the majority of the time it is.
Edit - Regarding game misconducts, I'm glad they're back. Gooning was out of control in 14. You can't just crush people like that all game long and have no penalty for it other than a quick couple minutes in the box. It was ridiculous.
