bumping this. There are already multiple threads about this and none seem to be resolved. Same scenario where at a certain time in a day, severe lag occurs generally during peak hours. This is happening at different regions and majority of these threads started after patch 6.05. What's more baffling is that there is no news about this and most replies from support seems to be a copy/paste template (given, after all it has been already almost 2 months since that patch and there are still no resolutions).
