A friend of mine had no DC problems until today. We joined open world, and after 2-3 minutes (both in open world and in battles) he got disconnected, and thrown to the login page. He rejoines, does whatever, then after another 2-4 minutes, disconnected.
The strange thing is, until today, he had no DC issues, yesterday he was on for 2-3 hours straight. And suddenly this. Was a small patch included in todays server maintenance etc. or something ?
Anyway, thought this be worth a mention here.
