Thank you very much for this wonderful detailed comment.
You’re invited to check my post regarding this exact “issue”, with a solution suggested.
By deserting Arabia and nerfing walls they basically create a counterproductive effect, people who used to go no-walls like Hera, Viper and even myself, now just wall manadorily. Games lead to mass TC boom OR extremely short one-sided games with no comeback mechanism.
Taking a look over AOC Arabia is the first step towards a balance game.
