We actually tried to replicate the penetration we thought we were seeing during our dunes match, and we couldn't do it. We did figure out that the combat log is not always accurate in telling who actually broke x part, so I think it's giving the illusion of penetration when really it is multiple mercs.
That being said, the merc isn't the only gun capable of lowering moral for the enemy. Really any gun has the potential to do so if the skill levels (not that number next to your name, but real skill) are skewed. Hwacha, Heavy carronade, flamethrowers, ect. All of those have a means of locking someone into a spiraling death that looks just as bad on our end as it most likely feels on their's.
I am of a firm belief that players need to want to learn from these kind of loses to really get anywhere in goio, as I certainly did when I started. It's also increasing telling that many simply don't have that want or patience to do so. I'm not calling them bad people, but that is just how that goes. Not everyone will stick around, but encouraging those who do switch up ships and try again has worked for us pretty well.
Basically, losing sucks. We all know that and have felt it during our goio careers. But it's what we do with that loss that determines what happens next.
