Your ping sounds perfectly normal connecting to Chicago. Using a speedtest is only useful if you think you’re not getting the speed you’re paying for with your ISP. It will use a server that is closest to you, so you can get the best/fastest connection (hence the 2ms ping). The other games you’re playing may also have a server in the New England area, providing a better ping.
Something else you may not be aware of with the Overwatch LAT stat is that it combines two stats they used previously, so it will inflate your ping by 10-20ms. Essentially, you’re getting a 30-40ms ping.
As for opening a ticket, I’d like to offer some info I’ve learned as a forum volunteer:
Getting 50ms latency is unlikely to be considered an issue. Something considered an issue is getting a ping over 100ms when it should be in the 50ms range. Blizzard also has no control over the routes your ISP uses to reach its servers, which can have a huge impact on your latency. All that being said, you are always welcome to open a ticket by clicking Support in the top right of any forum page.
But again, your ping seems great and I don’t think there’s any cause for concern.
