I have posted this countless times already
We have an issue with increased latency of 10-20 ms
All because, as you may remember, there were some Telecom routing issues and the whole thing became a big deal that lasted about a month
The players would constantly disconnect at random and the games would be lost because of it
The issue was "fixed" when Riot contacted Hrvatski Telekom on Twitter and they fiddled with some parameters or smth and from that day on we are suffering from increased ping and sometimes random lag spikes
With all my respect I ask you Riot:
Can you do something about this issue?
Riot Eambo helped us with this issue and we are forever thankful but the job is not done from the ISP's side
