I don't think your philosophy of knowledge gating is good. At the end of the day, this is not some kind of academic course where you need to follow things step by step and is something that is fundamental in understanding our world. League of Legends is not. It is a video game which people can interact with in multiple levels, from casual to extremely competitive.
I am not gating, i am saying if you can not understand it then maybe it does not apply to you. Anything below plat does not even need to worry about that shit; and i say that as a current g4. Who cares what sneaky, oddone, hai, daruis, ect is playing. They are doing things for reasons that do not apply to most players.
What is wrong with a person wishing to know what is what at more "professional" platforms of play? Nothing really.
actually you are wrong. Pro meta does not apply to lower meta. The inherit lack of skill for rotations and and understanding abuse cases matter in these cases. Hell most master and diamond players do not even play the same meta as pros, let alone how meta is different at each teir of play.
People that try to blindly copy X meta cause they saw it in LCS are usually a pain in the game. I saw zeonspartin split push top so i must also. These people forget that everyone is buy and warding and understand how to apply pressure on the map for a safe push.
The OP asked what makes Sion bad at high level play/why he isn't picked more often. The thought processes and reasoning behind something like that should be approached in a similar manner to how the OP did it.
Except the OP is counting on strangers to explain how things are working on a pro level. Luckly i have a logic and reason and great examples backing up my claims. The problem is that the OP has no way of knowing if i am correct. I may believe that i am correct ( most people on the boards do) but that is different than being correct.
The OP should of tried the wiki and checked the past patch notes and tried to figure out why X is happening. Odds are the OP has been playing through several patches (since it takes a while to level up an account) but can not put the information together.
The OP has basicly been hand feed now and does not really understand the problem or point. He knows that X conditions are happening but probably can not apply it other problems since he had to have it handed to him/her in the first place.
You think it does not hurt, i think it does. I am not against people going out to learn ( which this thread does not qualify as). This was give me answer, i do not want to learn, just the answer is enough. Learning would of been doing research in on game systems or trial by fire in the game. After experiencing failure and spending time trying to over come it; would of been learning to ask why X is happening.
