We have been seeing massive issues with lag and performance making the game unplayable for some.
Yes it's a double credit event but seriously if the devs are going to offer these events across multiple platforms at once then they should be ensuring their servers can cope with the demands placed on them.
I am due to renew premium again and this plus other commitment issues from the devs has me seriously considering not renewing.
Maybe next time offer the double credits on different days for each server.
