The effect of nerfs/buffs on gaining S rank for Mastery
The consensus as to what the criteria for S-ranks seem to be is that this is determined by ratios of KDA/CS/Damage dealt/Damage taken, in some unknown order or combination. This figure is then benchmarked against past performance of other players.
What I’m wondering is that if a champion is reworked or nerfed/buffed, how does this affect the ability to acquire S ranks and therefore Mastery 6/7?
For example, when Zoe released she was WTF OP, but has since had a bunch of nerfs. Are today’s Zoe players expected to hit the same numbers as Zoe players nearer to her release, when people were getting 1-shot with ease?
Or, as another example, when Katarina was reworked, her skill cap was raised quite a bit - were players at that point still held to the same numbers as pre-rework?
No doubt, as time goes on, the benchmark average is forever shifting, but it would still be harder/easier to get an S immediately after a nerf/buff, if the premises above are true.
