I know the basics but any tips?
defense - a star on each choke, with another just outside the site you're defending for a suck if they exec. this leaves one star for reaction plays
attack - smoke defender entrances, suck/stun common spots on an exec get box on A Haven or dice A Ascent. Abuse fake smokes especially for taking space and crossing sightlines. honestly just figure out where your team is taking and figure out what util you can use to help them out best
best tip is always try to have one star on you at a time tho, never place them all down at once so you dont over invest into a plan that might not work
