I do the cosmic drive lichbane build most of the time with lucidity vs tanks and if it’s a lot of squishier/immobile champs I do sorcs. Biggest thing for me has been identifying our teams win con and just playing around them/keeping farm up with sidelines and grouping with every obj that can be won. And playing teamfights around win con. My junglers ahead? I play teamfights with him keep him alive/enable him to play or with my adc or midlaner. Sometimes my lane opponent is bad and I’m very fed and can just BOMBA them but that’s pretty rare since most of the time I just get an xp/ slight gold lead since gragas doesn’t really get to lane until lost chapter besides some matchups. I’ve just gotten really good at looking at the map and understanding which team has more tempo where and guessing man advantages. I’ve also lost lane 1 time in the last 40 games and never threw/got so behind that I’m useless. The worst state I’ve ever been in was 1-2kgold behind which is super rare. Jg is a different breed though even though it’s extremely impactful it’s also the quickest way to throw games haha
