Read the context of the comment..... I wasn't even trying to compare league champions to that simple diagram. I said that older games had symmetries like that. And they did. The damage to a piece was the same at its base, but did 30% more to a vulnerable target but 30% less to a strong target. That's how RPG's BEGAN.
** I can't possibly do the math in League with 144 champions and a moving playboard with constantly changing skillsets... and items.**
In other words, League is a lot more complicated than my example, and realistically it is also impossible to PERFECTLY balance. However, I'm pointing out that with human guided computer knowledge, they could get far closer to balance than they are trying. With 144 champions, Hundreds of trillions of movement decisions per game, and some 120 or so different items, calculating balance is impossible. But, you CAN get within the proximity.
Guinsoos's does not create that proximity.
Youmuu's post buff does not create that proximity.
Champions with easy reset conditions vs champions who have none or difficult ones do not create that proximity.
Boots of Mobility in a game without Furor and Homeguard does not create that proximity.
Conqueror, Guinsoo's having inbalanced requirement differences between ranged and melee (2 sec vs 8 seconds is NOT balanced) does not create proximity.
Spear of Shojin does not create proximity.
You get the idea.
