To put it briefly, I regret this decision and believe that it does not contribute to clarifying the balance (or imbalance) of mages.
However, in practice, Castle and Swamp are not weaker than Tower, in my opinion. And pitting only overpowered Kiryu and Shakti against Solmyr is not a solution either...
