Is that a little "Badwrongfun" I see peeking through, Trampas?
More seriously, some people DO like the rules more than the roleplaying (I have a couple in my group) -- but it doesn't mean the playing stops when we roll inits. Sometimes critical plot points can happen IN THE MIDST of combat, as is about to happen to my players in the next game session (wink, nudge).
In the past, I've seen a fellow DM have the theft of a major artifact from our party happen in initiative time, as the entire group, NONE of whom were prepped with invisibility-defeating magics, tried to stop a person who stole an object and cast invisibility from leaving a room with said object, and breaking all Hell lose. It was the most DARNED ANNOYING time of my life, but MAN, was it fun!!!!
