I've tried playing astra a few times. When I was in silver I tried and it didn't work out, so I tried again in gold and I still struggle to play her.

When I play astra, I just feel like I don't understand the game well enough to use her abilities properly. Outside of smokes I feel like I have no impact and it makes me feel like maybe astra is an agent that is only really good in higher ranks. Is this true? What are your opinions on astra in lower ranks?
