I’ve had the exact same problem ever since the start of this week. I play on Gandara (EU) and I experience lag, the game freezes in combat and also when I don’t do anything, I get disconnected. It’s very random, sometimes I’ll be able to play for hours without a problem and the next moment I’ll be disconnected every ten to three minutes. I have tried to play on a different pc, but that didn’t make any difference concerning the disconnection issues.
