I'd love to know where you got that logic from my post. I said you don't need to read patch notes to play the game. I hate to break it to you, but you don't have to read the patch notes to know what a champion does either. You can either play the game and learn what it does, or even just see the champion preview to get a basic understanding of the champion. No where did I say you should know nothing about the game at all.
Chess is actually a great example supporting my case. In chess, there are literally entire books dedicated to the various moves you can perform as well as strategies that can be employed. At a base level even a novice can understand the basic function of the pieces. However the more intricate moves and strategies those pieces employ are generally beyond a novice.
Do you think chess players who don't have all the move combinations and strategies memorized should be looked on with disrespect? Do you refuse to play with people who haven't read at least one book on chess?
The same applies to League. I'm not advocating knowing nothing about the game when you play. I'm not even saying you don't need to know all the champions. What i'm saying is that you don't need all the patch notes and indepth detail. If I know how kayles abilities work, I don't really need to know she lost 5 base ad this patch. The same can apply to reworks. Garen has changed, but the fundamentals of his abilities are the same. The same applies to Darius and even Morde. Yes, you'd have to adapt to the changes, but so does everyone else. It might take someone who doesn't know what the changes a little longer to figure out the nuances (either more games, or them looking up the changes after their first match against it), but that's fine. I can guarantee you people who read the patch notes are still going to struggle to adapt to these changes.
Here's a question for you. Without looking at patch notes, do you remember what the most recent changes to Ryze were? What about Ahri? Tristana? How about Urgot. If you don't remember in exact detail the number changes, then why look down on someone else who doesn't know that information, but for a different reason?
