The benefits of Ruthlessness are:

• Free damage if they stay at range one of each other
• Forcing a skilled opponent to fly out of formation
• Preventing your opponent from being able to concentrate fire (as hir ships are spread out)
• Being able to attack enemy ships while they are isolated from each other
• Maximizing the use of obstacle placement and disruption, as any obstacle may force an opponent to take extra time to gain a firing arc on you, or to get closer to another ship
• Severely better match-up against Swarm
• Severely better match-up against Synergy

Pretty danged good, if I say so myself.

I want, like, 5.
