To show we didn't forget, here's the idea for a lasso.
It uses the Light Weapon proficiency. It does need to be "loaded" (which is mitigated by Quick Shot). If it successfully "hits", it does no damage, unless it is a critical hit, in which case it does a point. However, the target is now bound and can make no Actions other than try a Save Test to escape. (Basically, it works like the Web Trait of a Giant Spider.)
If you wanted to pull them in, that's something that could be done, but it'd likely be a contested roll or something like that to see if you succeed.
