I've started playing league recently, for past 3 weeks, I'm level 24 now, started off as jungle and started playing sett top (because he was cool asf) yesterday and really enjoy him. I'm just very confused because there's so much stuff I don't know, when to use which runes, when to build which items, I currently just use op GG and always go with the most popular build. Long story short, how can I learn and get better? just by playing more and more?
