What is on an ADCs mind when laning and/or after? What should be on ADCs mind but maybe isn't?
I'm guessing before you gain a few levels or even during loading screen you're thinking about how lane might play out. Do you think about other threats outside of your lane like enemy jg, mid, top teleport?
Early levels I assume you're looking at who has better cs, looking for trades, maybe looking at minimap a little. When you're pushing you do see when vision dies off but do you notice that supp has used his trinket up, has not got ss yet and you do have 2 wards ready? When you start roaming are you just looking for a kill? see somebody low in enemy jg or mid and you flash in n try to assassinate them? Do you think about where the other 4 enemies are, remember there are almost always 5 enemies, almost always trying to close in on you.
Think about what threats are out there and how fast they can make it to you (faster that you think most likely) Positioning it one of the greatest skills in the game. When you never walk into an area where Thresh can walk at you and force you away from minions and land a clean hook. Don't just think that when your hp is up that you can likely handle anything with flash and a dash. Mistakes happen, you feed and become useless. Just be more mindful. You can still make risky plays, that is how you snowball but don't make bad risky plays where the enemy has to mess up to not kill you.
Please help the younger ADCs learn basics. They learn the advanced stuff and skip all of the core concepts. Please share things that a guy with god like mechanics but is new to this kind of game needs to think about. How to use his godly mechanics and not feed bc "oh, he had heal" "oh jg ganked" "oh, they have a mid laner" "i forgot to heal" "i thought you were going to heal, really? 7 seconds cooldown? mb"
