She is a tanky support.
The Q can be used to push enemies away or into a bad position, help allies position themselves or escape. I think the most interesting application of it is to hit both an allied melee dps and an enemy hero, which allows the ally to start attacking. This is a very high skill ability and probably my favorite part of the kit.
The W is very powerful. If Bubble Orb ever needs to be removed we could reintroduce it through this hero. Still probably my least favorite part of the hero.
E is the type of passive that I like. While it's still a passive it's all about positioning.
R is kinda broken and silly but sounds fun. This ability should never exist in regular Dota but it could work in custom games. Seems good for OAA.
