I don't play a lot of Competitive but from the 7 games I've played this Act, I can see that I'm clearly losing lots of defensive rounds:

On attack, I try to get the spike down (hence the 7.00 Plants / Match stat and I play for trades. I use smokes and walls to get the spike down etc. On defence though, my teams would just get ripped apart.

(My Unrated stats are a lot more 50/50, so maybe I'm just overthinking it)

Any tips for doing better defensively?
