PAPA BLESS
Mmm yes, please. While Ling rounds aren't horrendous now, most of the time they end in horrorform- crew is scared and dying, but the horrorform is either murderboning and not being theatrically scary, or they're unrobust because roleplayers forget Horrorform is the most combat-based element of Changeling. The ability to queue for Stealth Absorbs allows for you to really hurry up if you're succing someone in maint, but feel like Security is coming or an EMT is running to them because you only now set sensors.
Now, for the part I love the most about this:
Making it so Changelings automatically get creepier and such the more DNA they have automatically sets the atmosphere for the crew, and the Changeling can go along with it, even if they aren't all too great at the horror aesthetic. By just changing their speech patterns to the scariest thing the player can imagine, they're already fitting the round for what it can be because the way they've probably been absorbing all round is already saying "Character isn't who they seem" and the player can adapt to it, either switching to more violent and more noticable murders in maintenance, or just switch their personality and go "Yes, I am a ling, and I am stronger than I was when I was acting just a wee suspicious. I am the Villain, and you fight me. Muhahahaha!"
