Home field advantage can make slappers harder to get out too. If the ground around home plate is like pavement the skilled slapper can bounce the ball high enough that by the time the ball is fielded there is no play at 1st.
Another value slappers add is putting pressure on the defense causing rushed and errant throws and pissing off the opposing coach. That is true value.
