Remove genetic things from lings entirely.

[DJ-Fireball_did_this]

Lorewise: Changelings are adept at mimicing human physiology, why couldn't their genes be similar? Hell, the two things they can look like are humanoids and monkeys. The Shambling Abomination is just a whole bunch of humanoids and meat thrown in a creepy pile.

Because they're just replicating the way humans look. In reality they're different. Their blood can move, they can eject stingers, they can change their entire structure at will, they're immune to space. They eat the genes and make their skin look the same but beyond that they have very little in common with a human or Earth mammal. Even with shambler when they just OD on human genes there's still a bunch of insect legs and crap.

Mechanics: Changelings with DNA powers aren't overpowered. They just aren't. They have no way of speeding the process up compared to anyone else getting the powers.

It's more to make them functionally any different from traitors.
