User blog comment:Nhan-Fiction/LEAGUE OF LEGENDS MUST EXPAND ITS BANNING PHASE/@comment-27200294-20160401214749

IRRC, riot already said something about this, and it's very similar to what you're saying. 3 bans for 1st pick and 2 for the last 2, to be exact. It may not address the imbalance ban, but it's a step in the generally right direction. IMO, 2 bans for 1st and 3 for the rest or your system would work better.

In addition, if riot is good at anything, it's getting appreciated for their input. They won't risk going full radical with the changes, so expect slow shift, lots of trial/error and pages full of context. I remembered they said something about documenting the impact of pick order on the rehauled system, though I could be wrong. So next preseason, perhaps?

Scaling ban... Hard to implement, how it would work in case of duo or matched against opponents in other tier. And then there's ranked team... I'd go without the scaling so as not to complicate things. The only problem would be raising the cap from 16 champ to 20 to enter ranked queue.

The rest, I completely agree.
