If you train your "elbow" skill like in the following form clip, you will have better advantage than WC. Some of the northern TCMA systems do train "elbow" seriously. There was a fight in an office that 1 person had to handle 8 opponents (small space, multiple opponents). Through the whole fight, the elbow striking was only used. There were no punch, kick, lock, throw, ground game in that fight.
In a phone booth, you may have to punch 3 times to knock down one person. You may drop one person just by one single elbow. When you deal with multiple opponents in a small space, 3 punches to a person may be a "luxury".
