The narrative of "astra is not a good solo carry agent" is quite annoying. She actually quite powerful in solo que. Let me break it down
Astra is the best lurking orb smoker in the game. That's a fact. However she is all so criminally underrated as a second third entry. Basically you just pop smokes down hit e twice and shoot heads. She doesn't need to be played like a chess game preplanning all your stars, she can be really proactive/reactive.
Smokes:
Really easy to use, full map range, one ways possible, great aggro option.
Stun:
Good for site hits, help secure kills
Suck:
Really really mindless postplant util, no lineups just pop down and in a 1v1 is a free take off.
Ult:
Ult is really good, secures free plant/defuse, cuts all info on the other side of the wall.
Luh calm yap sesh, shoulda used this energy on my college apps 💀
