Where did they say the patcher may be slow due to congestion? Because it runs off torrent. Unless, I'm going to assume the initial file, and thats why we have these stupid upload/download ratios to release congestion? Seems odd to relate server congestion to an torrent...

Edit
Ah I see your post, it will be for the initial download which then we'll seed together. Things seem to pickup after the planned maint when people come back and begin downloading/uploading.
