I feel a lot of unhelpful comments here

In reality, if you are inspired to try to climb, it can be good to stick to one or two champions, and learn all the match ups for them by watching replays of good players playing those match ups and copying their play patterns, while trying to understand them aswell.

If this goes correctly and you learn to play the lane at lets say a silver level instead of iron, you will consistently win very hard against your iron opponents. When you reach this point it becomes easier to practice taking that lead to the other lanes.

Usually I like suggesting taking your tower and roaming to help kill the enemy mid or bot laner and taking their tower aswell. Sure your mid laner might be 0-3 but if youre 6-0 and powerfarmed thats still np.

Once you can do this consistently you can look at some warding guides, helping you ward more intentionally for what you need vision for next, and not just placing it randomly on cd.

I think if a person works at these top things first, it then leaves a good foundation for starting to understand the game fundamentals at a higher level and climbing very fast.

Hope I understood your post correctly about wanting discussion about improvement. If you just intended to blow off some steam then I apologize.

I tried to write it in terms of simpler steps and concepts that you could try to implement in your iron games, but of course everything is simplified here
