I have received a lot of lags since the latest update. I think it was April 15 that I get the update that ruin the game.
Before that update I have never seen the little red dot in the upper left corner. Didn't know it was there.
It's not every match but some days it's about 50%.
Like I said, it's ruin a great game.
I have used PingPlotter to check if there is difference in latency to the WoT servers (Can't find address to WoWS server). But it's pretty mush the same everyday.
Is it just me?
