You need to kite properly. Regardless of having sustain/defensive items/abilities or not, the key to success as an ADC is proper autospacing, especially if you are building full glass cannon.
For this game, you took too many free damages by standing still between AAs (e.g. standing still in front of a Rumble's flamspitter, clearing minions while they are in melee range); it's shown through your reliance on the use of net, as there are several instances that you could've saved the skill by positioning and kiting properly.
Another that I have noticed—which I could very likely be mistaken—is that you don't really toggle the scoreboard to scout for the info of the enemy (default key shortcut is tab). This is crucial. I check the scoreboard at least once every minute to gain insights on what items the enemies are building and how my team mates are adapting as the game progresses. It seemed like you bought a basic LW at 15:55 mark without even knowing what armor items that the enemies had; it's likely that you could've benefited from completing your Runaan's first and get LW for the next back.
Here is a summary of a two scientific journals that discuss, "the validity of the assumption" of life being exponential. https://www.jstor.org/stable/1266533?seq=1#page_scan_tab_contents
Here is a list of examples where the phrase is used in several scientific settings. https://ludwig.guru/s/the+validity+of+this+assumption
This is a number of scholarly articles all discussing how valid assumptions were, not how correct they were.
Each of them is completely interchangeable with the way I have used it.
You wish to discuss how valid (the validity of) Jhins assumption was.
I am speaking about who was responsible for making it. The fact it was an incorrect assumption is not up for debate. It is a known quantity.
You also compared something I said (which makes sense) to something only you have ever said which doesn't make sense. It is at the very least difficult to understand English.
To break it down
The validity (soundness, reasonableness, rationality, logic, justifiability, defensibility, sustainability, plausibility, viability, bona fides, effectiveness, cogency, power, credibility, believability, force, strength, weight, foundation, substance, substantiality, authority, reliability) of the assumption, is a perfectly coherent statement. The only thing is lacks is context. The validity of Jhins assumption. Given that you are absolute drowning in context, I thouught you could deal with a single pronoun. I have now replaced it.
