Started to play Astra as I recently unlocked the agent, and to be honest I only played her for a joke but then started to realise that I immediately fell in love with her.

I understood some of her abilities faster than any other agent, and was quickly getting info that I was making multiple enemies vulnerable, blocking always 4 - sometimes all enemies with the majority of my smokes. However I rarely use the concussing ability along with her ultimate. Not exactly sure how to use it to make an impact for the round for our team so I usually resort to blocking entry on 2-3 sites when defending on start of the round.

Any other tips and tricks I should know?
