I can definitely blame an ISP for such issues actually (Bandwidth throttling is a thing after all). And the fact that such issues seem to plague mostly the same users time and time again (Speaking about IRL friends and even some ppl who write to our support team. People who are in the same server as others and still are one of the few to have such issues on a particular server), while others haven't even heard of something like this ever happening, gives a pretty good hint as to the nature of that which causes these desyncs. Namely the Web connection.

I exclusively use my mobile provider's network these days exactly because of such issues. While my home network is good enough for MMOs and online games I still experience some nasty latency spikes even though I'm not getting DCed right off the bat. And I won't even mention what was it like to try and play Top Eleven on that network. On the other hand I have some great Upload / Download speeds.

Damn I even go as far as tethering my laptop to my android sometimes.

Top 11 is definitely a bit sensitive to packet loss and connection timeouts (and a ton of other apps I play), and even though our servers try to compensate, the situation can become unmendable at some point.

That's why we ask that anyone who encounters such issues should write to our support team. Because, yes, it may be due to the ISP as I said, but we recognize that it can be caused by our side. My experience here so far shows mostly otherwise though.
