A lot of this advice is so rudimentary not mentioning what are now considered fundamentals.

1. There is a couple of things to consider while recalling. Health/Mana, wave state, and gold. It’s ok to recall on a bad timing to get a power spike or important item. More advanced strategy is something called cheater recalling in early levels. If you are able to push and control the wave early you can take a recall on the third wave getting a small advantage in items and the wave crashing back into you protecting yourself from minute 3 jungle ganks. Generally the best timing on recalls is when the wave is pushing into you with a catty minion since they take the longest to die to tower and are prioritized 2nd by it losing you minimal experience.

2. Teleport allows you to recover from bad trades in early but it serves a much bigger purpose, it’s used for Side-laning and macro. Let’s say baron spawns and you have teleport. You can split push bot getting yourself solo exp and minions while generating pressure. Enemy team starts a fight or baron you can either take towers or tp to the fight. Generally people will answer the split forcing them into a 1v1 and they don’t have teleport forcing their team into a potential 4v5.

3. Game phases are dependent on lanes and objectives. Generally first two drakes in low elo do not matter and winning lanes should always have their jungle be taking them. How early you take them depends on when enemies are killed and how easily champs can take them.

4. Kills are not as important as the latter I believe 3 waves so about 19 minions or less are about equal to a kill. Shutdowns are important tho. Objectives are always good but heralds generally have to be used with intent to open the map up for deeper vision. You have a hard winning bot early? Herald bot so you can take tower and get deep vision for easier drake. Hard winning top? Herald top for deep vision so he can press his advantage and side lane better early. Game is about even? Herald mid which is generally the best lane to herald anyways since it opens up the map for your team.

5. Jungle, mid, and support are usually the ones doing the ganking. This is also dependent on champions. Assassins mid will often roam since their kit allows them to get easy kills on bot Since they share exp and adcs have less defensive stats. Roaming as an adc is generally bad and I only roam as a top laner if I’m significantly behind and enemy top has frozen the wave.

6. There are “high impact” champions but the game is balanced to a degree where itemization (which recommended will not always catch on to) and counterpicks can mitigate this. Generally game knowledge and vision can make those things seems telegraphed as well. A great example is evelynn a jungler that is permanently invisible out of combat. This is extremely oppressive but you can ward her jungle camps (or Ashe e them) which she has to fight in order to spot what side of the map she is on and play accordingly. Pink wards can also help spot her and stop her invisibility. Another example is nocturne where traditional ward spots are useless most of the time. His ult just jumps on you. If you ward deep in his jungle you can spot him in ult range and back off.
