"There's nothing new that Nemesis Draft can show us in terms of balance, popularity, etc that the Balance Team won't already know."

So they knew about the balance issues and have refused or are very slow to address them.

Sorry, but I take issue with that. I'm so disappointed with the Balance Team. Something as obvious as Mobility Creep running rampant in the game with little being done to address or fix it.
