If you're like me, your thumb speed is too slow and your index finger is slightly faster, but still can barely succeed in taking a dump so you can collect the feces for battle later. It does just enough to make full use of Dragon's Breath if you're playing the Mage class, but you'll struggle when you have to destroy the big black anal probe and beat Cartman or Kyle in a farting beam struggle.

Now I play with a controller and some users prefer old school keyboard and mouse. You can use both at the same time. When it comes time to mash A on your controller or mash S on your keyboard, mash them both. Any tough button mashing segment is over in a few short seconds.
