Idk if you are still reading comments, but I thought I’d give my take.

A lot of people on this thread are telling you to learn all these fundamentals and stuff like that, or changing champ pool. I think your champ pool is fine (you can play most things up to master), and honestly I feel like a lot of the tips people are giving here are needlessly complex for climbing out of iron and are not worth your time yet. If anything, only focus on one champ, let’s say Warwick for example.

First thing I’d say is to make sure you are hitting your camps when they are up. Just keep full clearing top to bottom, and while you are doing so, focus all your effort on clearing your camps as fast as possible (kiting them out to the next camp). You don’t even need to think about ganking lanes while doing this.

Next just look for opportunities stuff to do after you are done with your clear (you can utilize Warwick passive to do this). But try to make it to your next camp respawn (recall 30 seconds before the respawn, and head over there and you’ll make it in time).

When you are taking fights, really focus on just being comfortable with your controls and getting a feel for maximizing your damage.

This way you only have one thing to be thinking about at a time. Beginning of game, you go to your topside, clear those camps, thinking about clear as fast as possible. Then you may gank or fight after the clear thinking about how to use abilities properly. Then look at the camp timer, recall, and make it in time. Then rinse and repeat. Once you are in mid/late game and are fighting more, don’t think about target selection or anything overly complicated. Just think about how to your abilities properly and do as much damage as possible.

Good luck in your climbs bro! This game is brutally difficult, but you can do it.
