Well, I'm testing the changes in Master Yi and so far these changes are not so good. Here are the changes that I think would work better:
1- If Riot is trying to make Alpha Strike more useful in situations other than using it as a dodge skill, the 4 hits on the same target must be followed by a base damage increase, or increasing the scale damage to 110% for example.
2 - The cooldown of Alpha can be reduced. I think it would not be broken because the Q's CD is very high, especially in the initial levels.
3- If the Alpha CD is low, Rito could increase the "%" of the Highlander CDR from 70% to 90%.
4- The change in Wuju style was very bad, removing the 10% of bonus AD AND lowering the true damage scale percentage was a bad idea. It seems that the champion lost a lot of damage and was much weaker than the live. PLEASE, REVERT IT
In short, I think there is only one decent change: the casting time of Alpha Strike and Meditate has finally been removed. The 4 hits of Alpha Strike would be a good idea IF had been followed by another change, such as more damage or less cooldown. Otherwise, Riot should reverse the changes (only keeping the change in release time). And I think E's nerf was one of the things they could do with Master Yi.
