So... you're taking the "I'm smarter than I perceive you to be, so I'm not going to continue" end? Legitimate question: If you perceive someone to be less able to make the 'correct' jumps in logic and so you disregard them how exactly do you think they'll get better at making said correct leaps?
And also: I'm sorry that you think balance shouldn't be directed at high level play, but no, it should to an extent. If I had to choose one (1) type of player to balance for, it's the top players - because they're actually good enough to properly utilize the tools they're given. If I make a champion designed for coordinated play (Shen) then why would I balance him without coordinated high-level play in mind and instead make him usable in a level of play low enough that they can't properly take advantage of his strengths? Again, this is if I had to choose one (1) type of person to balance for in regards to specific champions. For champions designed for coordinated play they should be balanced around said coordinated play, preferably at a high level because they're capable of utilizing that champion to his fullest potential. You can balance a whole game around as many people as possible, but after a while you have to admit that certain champions simply have to be balanced around different skill levels - Shen is one of those champions. He will simply never be as valuable in uncoordinated play as he is in high level coordinated play, assuming viability in his current balance. This means to prevent warping higher level play to the point that he shoves out other picks, he can't be balanced around lower-skill uncoordinated play without keeping high-level play in mind.
Anyway, balancing according to the whims of a community, I've learned, is an absolutely terrible idea.
Now, you say can give a list of points, well, why don't you? This is a forum - it's meant for discussion. But for some reason, you eschew discussion because of what you perceive as bad logic just because it isn't your logic.
