Well her passive seems meh to me. I mean this speed boost is kind of nice, but also not the best passive you can have. It is of limited use occasionally only.
Her tactical has quite a long range, and since it's got 20 seconds cooldown also with chargeup time on the recipient you need to time it. But the fact it works through walls makes it quite long range and easy to use. I don't know if this can be a tide turner in a heavy match, but for sure it has its good uses as life saver.
Her ultimate has also quite the long range at which it can be deployed, which can be interesting. The batteries, which do create her ultimate, do have way too much hitpoints until one is destroyed. I do expect a nerf to them coming in the future.
So her kit is quite straightforward to me, nothing to complicated actually.
Personality wise she's annoying as hell. It's like you've put a chipmunk into the game, or one of these positive life coaches spreading fake wisdoms around the internet on crack.
