I spent the past weekend playing a new mech game, Hawken. One of the game's signature weapons is a powerful RPG, which has a short cooldown. During intense battles, I often found myself spamming my RPG button, just as I would spam Mutilate while playing my rogue. I wanted to make sure I used it as soon as it came off of cooldown. Unfortunately for me, pressing the button a second time once the RPG is airborne causes it to detonate prematurely, which usually resulted in the RPG's explosion damaging my mech instead of my target.
While raiding in Dragon Soul, combat was the spec du jour, you had to spam your Sinister Strike key. If you weren't fervently mashing the '2' button on your keyboard, your energy would cap and you'd be throwing away free DPS. What's worse is that combat's favorite stat was haste, which only served to exacerbate the issue. Rogues weren't spamming their keys because they were impatient, they were spamming their keys to do their job.
