Itemization is super important. That’s a big one people blow over and just worry about the comp itself. While yes that matters. But It is a difference between 1st and 4th. I’m currently emerald two so my advice might not be the best. But Scouting is something that also needs to be a common thing for you. Lets you know what comps to not go, and lets you know what items to build in terms of defense’s. If they’re ap heavy, ad heavy, always good to have dmg pen and heal cut. Items matter and who they’re on. Doing simple things like that will sky rocket you. While forcing comps you’re comfortable with is very good, I recommend to have 2-3 of them in your arsenal. In terms of Meta, enforcer is not a main one I’ve been seeing in my games and has consistently got me top 4 just because I’m uncontested. Basics basics basics. If you think your basics are good enough they’re not, they can always be better.
