Recommended Item Sets = No?
So I haven't played LoL since 2016. I was a player who used the LoLbuilder app that would allow you to install builds directly into the game so you could follow them in the shop. Sadly the website has been shut down and with that I'm also guessing the app would fail even if I could find it.
So now to the point. Can I reliably use the Recommended item sets or am I going to have to read long guides on how to build characters? I fear the later since I think that would mean I would have to hold like 5 guides in my head just to play this game (one for each role).
