The balance's team player-cards do not matter. And there's always a bit of ninja'ing in every patch. The modders introduced themselves in the forums and were engaging with players during the months of the feedback-loop. They did everything great.
They had their own little agendas when it came to certain things. Their hands were also tied by Relic on many things.
Saying they did everything great and were open to discuss everything is a lie. They did great things with the mods and patches, but they often ignored things that went against their personal or relic's wishes.
It is also interesting that you say the balance modders's playercards don't matter. It seems anyone trying to make balance suggestions, needs a serious player card. Those calling the shots suddenly don't? Or are you saying that half of the balance team, like MR Smith, only play team games and primarily allies?
I am a known fanboy, yet the balance modders are somehow immune to such bias, even when their actual playing history indicates to such a mental state.
