Has WPT been lagging for anyone else?
Could you be a bit more specific?
Try looking at your 'Task Manager' (if playing from a PC) & you'll see that WPTglobal is a HUGE resource hog (it'll be using up a large % of your CPU).
While running WPTglobal my experience has been that I need to limit whatever else is running on my computer & if I don't, I will run into lag issues.
Hence why I rarely play on the site
