When you are medic and heal others, your Medic will kneeling down and play animation to treat patient who is down even when your patient are standing right next to you.

I notice same kind of problem while i was testing repair specialist. I destroyed one back wheel of my car and tried to fix it.
My mechanic was standing back of the car about meter or two away of the car and was fixing something invicible.

It would be nice if this kind of weird placements could be fixed somehow.
