Two points from me about the speed boost.
1. It is the holiday season, so the speed boost may help many players who are pressed for time and still trying to get the consecutive days played bonus in.
2. It appears that many people cannot find the menu/game settings/options button. This will bring them to the forums to find out how and that the forums can be a great place to find help.
Thanks WGT, I happen to like the speed boost on occasion just to spice things up a bit. It can be a blast to turn it on in the middle of a match just to mess with your opponent. :-)
