This removal of compatibility between the Core Metacs alone broke the Root of Life as a viable Core Metac, as without backward compatibility, they could no longer work together from Rank 1 to Rank 5. They were essentially different Core Metacs now and would reject each other within the mortal.
In exchange for this madness, he had more room to change the Core Metacs. Without worrying about compatibility, one vibrating string from Rank 2 to Rank 5 was freed up for extra functionality.
After he broke the compatibility, he picked up the Rank 1 Core Metac and tweaked its functions a little bit by changing its abilities from (Extract and give life to disciples) & (Enhance the disciples' power) to (Extract lifespan and Enhance disciples' power) & (Fuse with the Energy Well). So it still had only two vibrating strings and wasn't a Rank 2 Core Metac yet.
This was against common sense, as only Rank 2 Core Metacs should fuse with the Energy Well. But this was just the start.
