Several russian players (me too) cannot connect, or have lags 5-10 seconds after every action, often disconnections
I suspect that this is somehow connected with the pro-league (that now sending a full battle log to servers?), because while the pro-league did not work, everything was in order.
Moreover, the last day of the last league saw such a screen for the first time, it was not there before.
Right in the middle of the battle many times reported that the connection is lost, and stopped the fight (it was only in the pro league!)
Such a screen hung for half a minute, and even for a minute. Fortunately, each time the battle continued.
