Changelings, and why they're just too damn powerful

8 lasers is Not even halfway enough to put down a changeling

Having been on the wrong end of a laser as a ling, it definitely is way more than enough. Now, how long they stay down is a different story, but in my experience the crew absolutely loves to gang up on obvious changelings that can't run away (just look at shambler dogpiles), so you only need to incapacitate them for a short time to call down a stampede of welder-wielding graysuits on them.
