They had no idea what they wanted to do with Ferengi in this episode. By the end, they are downright feral. Wearing furs and jumping around screaming like cavemen. After watching them in later episodes, this one just feels really weird to see.
I forgot that detail lol. Let's take energy weapon technology that can shoot in a perfectly straight line...and artificially limit its range and utility.
It might be a similar line of though as the Goa'uld weaponry from SG-1. They aren't meant for accuracy or range. They use weapons of terror that create an absolute massacre when they do by chance hit.
The Ferengi, and especially of that particular group were Ferengi pirates of some sort, probably wouldn't be above such tactics.
But also it was very clearly not a well thought out episode, so I'm absolutely applying meaning where there is none.
