Remove genetic things from lings entirely.

[DJ-Fireball_did_this]

There's literally nothing that says they don't have genetic structure capable of using genes implanted in them in the same way a human would, especially when taking human form. You're trying to make up backstory and information about a creature that part of the point is we don't actually know how it works. The best we have is that it escaped from some sort of bio-lab that Nanotrasen runs, and even that much isn't -that- clear, it's just from the printout that happens at the start of the round. Your headcanon isn't necessarily true.

It's not "making up backstory", the game says their true form is akin to a shambler which looks like a bug. And they do a bunch of utterly inhuman things when in human form. And we know that genetics is good for human-y things because NT supplies medical with them. So, logically, a changeling should not work with SS13's on-site genetics technology.

I mean. One could argue that Wizards are also this, as well as...literally any antagonist that isn't a blob? If you really want to reduce it down to "An entity that is given tools to do bad things to the crew"? "Instead of traitor items they get spells" "Instead of traitor items they get vampire powers", etcetera. 

An antagonist is generally somebody who has been given special tools and a griefing license. Different antagonists are given different limitations and tools so they're different from eachother. The problem is, with the current tools ling has, it's not very different from traitors. This isn't a blob-exclusive thing. Except maybe like spy compared traitor, all of the antagonists have different abilities and limitations. And even those two are given different objectives. None of this is even the point. The point is you're moving goalposts. So far I've been told that ling is different from traitor, and that all of the antagonists are traitor. Which is it?

I've found that actually, most people try to complete their objective as an antagonist unless they're a traitor with some particularly difficult or boring objective. It gives a good structure to what you should do. Changelings/Vampires especially do, as it literally benefits them and makes them more powerful to do so.

When was the last time you saw a ling that didn't just use all the same non-uplink objects to kill everybody? Yeah sure ling has powers but they're not that big of a difference.
As noted, memestings are just a sleepy pen.
Shambler lasts really short and/or is almost only found on the shuttle.
Limb critters never do anything besides get ignored via crew apathy.
etc.
So that loops us back to the objectives. Which are different from traitors technically but in practice it's about the same. It's still "kill people" but with the added step of eating them. Traitors are really the ones with interesting objectives, but they frequently just resort to killing everybody. Ofc they can get away with it since that's kinda their gimmick.

I think you're the only one who thinks any of the replies to you have been nonsensical. There's really no point trying to convince you that you're wrong here, I guess, aside from the fact that I don't think a single person has really agreed that this should be a thing. It sounds to me like you got fucked up by one or a few changelings with Genetic powers and like...I'm sorry, I guess? That's not a good enough reason, though.

Well, that didn't happen. I'm not sure what to tell you beyond that.
