For your third ppint, it would still only effect her visual range. So if the horde is large enough, she's not going to be able see all of the Grimm. Its like when you sit in a room and look at the wall which is 3 metres away from you. You can peripherally see where the wall meets the ceiling, but you're not really looking at it. The same would apply here; the higher she goes, the larger the area of effect, but she has to jump super high to actually get a whole horde in.

Not saying she couldn't, but she would have to.

Also, about the suicide mission...the lyrics of Red Like Roses Part 2 do say she made a sacrifice, and how she doesn't want Ruby to do what she did. She may have taken a suicide mission because she was first response, or the closest to it. So backup was on the way, but she knew there was a high chance of dying before they arrived, but also that someone needed to get there asap and take out as many Grimm as they possibly could.
