You don't know what you're talking about when it comes to mousepads and gaming. The reason why this mousepad is big is because there are gamers out there who play with low sensitivities who actually use about 90% of a mousepad that size.
Also friction on a mousepad is really all preference. Some people like a really smooth mousepad and others prefer a really rough mousepad, you shouldn't say that this is a bad mousepad because of it. I have used this mousepad and I can tell you it is a great mousepad if you don't mind a bit of friction and play any FPS competetivley.
