How will Riot avoid balancing champions around a specific keystone?
I'm sitting here thinking how amazing some runes are on certain champions. For example, Glacial Augment applies the melee slow on GP Q. When some options, such as Kleptomancy and Glacial Augment have special synergy with a champion like him, it's going to distort the landscape and make him much stronger when he chooses them over others. This will lead to nerfs and then he will be EVEN LESS capable of going alternative keystones since he was balanced around super synergistic runes. This cycle would defeat the entire "playstyle" concept of runes since you'd then need to go the 1-2 absolutely strongest for your champion or you are no longer playing a viable champion. How can this be avoided? This happened last season too with DFT and Fervor for example.
Gone are the days of 
, that way their close ties to the keystones itself is removed. Besides, those interactions almost always had been very toxic in the previous seasons as well.
