I will still play tourney , even with ranked match changes in place.

Also, it seems like very mild exploits...considering the winners haven't exploited it? Yes there is a fair degree of luck/chance involved, but no matter what the format is, people would be strategizing as they do now. In any case, I do not think the system has been abused, and the very fact that tourney was the fairest area of the game during the time regular matchmaker was being gamed, should stand testament to the fact that despite not being perfect, the tourney is robust even it its simplified form.
