Qiyana's W Behavior

I'm not sure if this is where this post should head to, I don't think its quite a bug but it feels like it needs to be addressed. So, Qiyana's W behavior is kind of frustrating where it is in the game and I'm not sure how its supposed to behave.

At present, there doesn't seem to be a noticeable trigger for what element Qiyana picks up when she W's towards a brush or Health Patch in ARAM, or a brush in SR. About 85% of the time when I W towards a brush, it picks up earth not wind (plant? I can't remember right now). In aram, the same occurs when W'ing towards a health pack or the brush. About 50% of the time my cursor is ON the BRUSH or HEALTH PACK and it still picks up Earth, the other 50% its on the wall and it'll still pick up earth or sometimes Wind.

It would be great if you could smooth that out or at least specify whether its where the cursor is or if its based on exactly what you're dashing too.
