What's the point of Sissy?

She can't trap anything, she's bad at chasing unless you go full scout/wireframe. Her poison does no damage unless it's lv 3 at which point if you choose, it can do VERY LITTLE damage. It only has 3 charges covering very little area and reloading those charges takes forever and can only be done at very specific spots.

Her damage is insanely shit, her blood gathering is about as average as everyone elses including johnny if you want it.

Johnny is a better hunter, HH is a better trapper and chaser... everyone does more damage than her.

What am i not getting here?
