Knowing every match-up with complete accuracy would require knowing every aspect of the game. Every-single-one. Nobody does. Not even TN. Like you said, they have "solid suggestions." Suggestions, for the record, are not complete. Suggestions are theories based on observation. And that's what they have. That's what a lot of people have, only to varying degrees. Thus, if anyone has any recommendation or insight on a buff/nerf, by the prerequisite that they have complete match-up data, there is not a single soul who is qualified to suggest any nerf or buff. You're talking about degrees (interval), not binary variables. By saying "ENTIRE cast at match-up level" you are saying "Complete (entire cast) match-up knowledge = 1" Again, complete being every-single-thing accounted for, which no one has. So obviously, that variable is always 0. For everyone. At least right now (and feasibly forever).
