I followed this thread when it first kicked off as I was experiencing the wild and crazy ATT lag like everyone else. Since it was largely resolved for most users, I haven't seen any more issues. I haven't yet (knock on wood) had my latency issues return.
That said, when the server went funky a few minutes ago, I had to hop over to see if it may be related. Like n_n's post, my friend was playing frontlines and got kicked. When he returned, whole alliances were missing from the match. About 5-10 minutes later, while I was rearranging hot bars, I got the boot too. Now waiting in the queue.
Just adding my voice here that the server connection and latency issues experienced in NA these last few months have been seriously concerning. As someone with thousands of hours, these past few quarters have been the worst condition of quality and reliability I've seen so far. I've got my finger's crossed that it gets better.
