So I just recently came back to the game (maybe 3 weeks ago). And ever since then I've been getting randomly disconnected with absolutely no prior warning and no accompanying lag.

Seriously. I'll be fighting something. Going through my rotation just fine. And then BAM disconnected. Never seen anything like it.

I'm able to log back in as soon as the data center stops showing me as already logged in which usually takes 15ish seconds, and then I'm fine for a while. But this problem doesn't seem to be going away. I've already gone through two server maintenance periods that aimed at increasing stability and there's been no apparent effect on the issue I'm having.

To answer the obvious questions, my Internet connection is fine, my router is fine, and I'm connected directly to it (no wifi).

Location: Chicago, IL
ISP: Comcast
Speed: ~25Mbps

This is extremely frustrating.
