Hello - Help

I would like to start by saying what a huge fan I’ve become of LoL! Absolutely love the game and the community.

I am level 31 I currently own 23 champions and I play the following in the same order, Kayn, Darius and Nasus.

Kayn - I’ve found Kayn a lot of fun but very difficult to play him as I don’t jungle. Never got an S with him either. Darius - his the most OP class I played, it’s fun, how tanky and with great DPS.. I got so many S’s with him I truly enjoy it but it becomes boring if I over used it. Nasus - extremely boring in the early game and very very slow champ. But late game his awesome, quite enjoyable.

I am currently trying to learn more about LoL so that I can start playing ranked. I am trying to learn the basics. I am currently readying about the differences in AP and AD and how to counter. I am trying to learn the strengths and weaknesses of champions but it’s quite difficult to do so until you play them all. I am trying to find a clear list of champions that are AP and champions that are AD but I can’t seem to find something accurate.

Basically I am trying to learn LoL so that I can play ranked. I usually play very very good in normal games but in ranked it’s totally different.

I was hoping someone could help me understand the game better and bounce some ideas and tell me a few tips about what I should look out for or look at more in order to better perform in games.

I have a limited time I only play 2-4h in the evening on a good day sometimes none. At work I’m super busy but I am very motivated so I started readying about it more now.

I like assassins, tanks and marksmen. I find assassins hard to play because their squishy but they have great dmg. I love tanks for the durability but they are very slow and heavy. I don’t have an opinion about marksmen yet but I like the idea.

Any advice or help would me very much appreciated.
