ITT: People who want to be a competitive DPS in anything, who also click, in denial that them clicking almost everything has maybe a 5% decrease in overall DPS. Also... 5% isn't a small amount over the course of an entire fight. Imagine if all the other people in your entire raid could do 5% more DPS... you could do heroics, or the last boss on heroic. It's a big deal, and if anyone wants to be competitive/TRULY good at the game, then you wouldn't click at all (unless it's like a buff or a mount). Sorry if this is seen as mean, but it isn't mean if it doesn't offend you.
