Why aren't there 6-player fireteams in patrol? (Destiny)

I wonder, why aren't there 6 player fireteams? What was the reasoning for that design decision? I have trouble believing it's because more than 3 people are too powerful for public events as instances with public events often have that # of people in it. Is it because patrol missions would be too easily accomplished, I doubt this too as they could be adjusted based on the # of players in the fireteam, except for the scan a specific location, but then they'd just be saving time if they were spread out.
