What's with the conditioning rune being nerfed?
It stands clearly above all other runes in winrate
In 10.6 for example, its at 52% (the next closest runes are Approach Velocity at 51.3%, Guardian at 51.1%, and Glacial at 50.9%). Keep in mind further that two of those are keystones, and therefore are supposed to be more powerful and can influence winrate more with smaller tuning issues - so you can imagine how powerful conditioning must be. I expect we might need to go harder on it later.
