There is no point when Sejuani can ever be optimal over Amumu when he still automatically does her job better due to Cursed Touch, Despair, and better scaling; Thresh is not going to do Blitzcrank's job better when a Thresh grab on a carry is at best an initiation while a Blitz grab on a carry almost guaranteed death with a team behind it.
Some champs are just inherently better than others. Those mentioned in the title are pretty much the worst offenders. There is certainly some power creep going on, but I think Riot is trying to curb it a bit by introducing 'weak' champs like Nami, Thresh, and prebuff Syndra. It doesn't fix the problem at all.
I honestly think draft will fix many of the problems with OP champs. The new meta will settle, and yes, there will be a top tier, but it won't be unstoppable.
I realize cheesecake keeps the current top in check, but the difference between cheesecake and top is much greater than the difference between top and mid, IMO.
