Rather than leadership, lack of time was a bigger factor imo. BTW we had a stable/accepted UU list, the gen was practically over and BW got announced.
If you want NU to get up and get going, you first have to get UU going, and hope that we don't take as long with tiering as we did in DPP.
Regardless, even the current system could definitely use some syntax work to make it more clear and less confusing-- even if you keep the same names, distinguishing between OU as metagame and OU as UU ban list would definitely make things make more sense.
