Scholar
With the disappearance of Janna, the Scholar system in Truth Arena season 6.5 is not popular with players if key units like Renata or Silco are too strong.
Specifically, at the 4/6 Scholar mark, the energy recovered will increase from 10/20 points to 15/25 points.
Idol
In fact, the effects of the Idol race itself will not be affected at all in the upcoming patch 12.7.
This change will help squads using 3 or more Idols to solve the problem of being too dependent on a certain main force while this ethnic unit itself lacks damage.
Yordles
If we look at the changes since season 6.5 launched, we can see that Riot is making an effort to make Yordles stronger and move away from just being used to improve gold.
Therefore, in version 12.7, Riot had a buff that seemed small but was actually very large when the energy reduction index for casting spells at 6 champions was increased to 30%.
