These manager pair selections have got to be a joke. At first, I thought that its better to stay silent and let it pass, but on reconsidering it, I think it sets a dangerous precedent for the future. From what I understand, there are two primary qualities that the host looks for in any manager that has signed up.
Competence and experience in said tiers
Team chemistry /Ability to lead a team
One can argue about the weightage of said qualities, but everyone agrees that these are what every manager should have at the bare minimum. If you sign up to manage, it means that you back yourself in both these departments. Its then the host's job to use their best judgement to pick the best out of the bunch, for the overall health and success of the tournament. That does not seem to be the case here.
One look at the manager pairs, and anyone that has been keeping up with ZU in recent times will tell you that something is off.
