Not playing in NA, but after 4.1 my boyfriend and I kept getting utterly random dcs only in XIV, and it got worse before Xmas.

After trying all the voodoo we could with the router, we bit the bullet and bought a pretty expensive Asus router, and used our old router as a modem. The dcs stopped after that.

Our theory is that SE changed how the game sends packets and our old router was ill-equipped to handle it.

If you got spare cash, this is worth trying. Good luck.
