If you are a clicker, yer a keyboard turner, which means in the long run, any buttonmasher is going to outmove you WHILE being able to cast spells/abilities.

One of my guilds tanks was a clicker, he pushed a solid 500TPS... I converted him to buttonmashing and he became a 1000TPS machine. You can't click 3 buttons at once, which at least for classes like warriors is important to be able to do. (Heroic Strike, Shield Block + whatever ability is using your global.)
