How much should be allowed in replay? Keep things as is? Allow for replay on outs as well?

IMO, balls and strikes is too much, but this idea that it upsets the flow of the game, when there is so many pauses in baseball from shaking off signs, to meetings at the mound, to stepping out of the box, to the inevitable 3-4 minute theatrics of a manager arguing a call (where replay would likely save time wasted instead of increase it), seems just foolish at best.

So TC, what do you think about the possibility of video replay and the "human element" of baseball?
