When I first started, I never used a mousepad. I played on a wooden table when I'm still using desktop PC.
But when I started to bring a laptop (not mine, but my sister's... ;_;) and traveled around, I'm having trouble playing it on various surfaces since different surface gives different experience. Some surface makes the mouse movement too fast and some makes it too slow, so I have to adjust in-game mouse speed multiplier between 0.7× to 1.2×.
After my bro bought Razer Goliathus Ω (Control edition) mousepad, I started playing with it and it really gives a whole different level of experience. This is where I started to think that I should get myself a mousepad as well. So far I still yet to have one even until now.
Now that I'm back to my hometown, I can only play this game at Internet Café. The Internet Cafe has Razer Mantis (Speed edition) and it almost has no difference of experience to my bro's mousepad.
I also am having trouble playing this game with different mouses, some are cheapo (and might not work on certain surfaces) and sometimes borrowed my bro's Razer Abyssus for fast spinning. I'm thinking of getting 2 mouses: Logitech M125 and any gaming mouse (preferably Razer). The Internet Café has different mouses as well, so I have to be picky on choosing a PC with Logitech M100 mouse, as other mouses somehow has built-in Mouse Cursor Precision mode (despite it being Logitech mouse as well). lol
