The way it is now is perfect, I hear a lot bitching around, but I remember clearly when they had an update and I suddendly was mg2 from nova master and felt pro, while actually it got easier. I heared there'll be 1 more update where they will make it even harder, but might aswell be rumours.
Right now im DMG/Eagle keep ranking up, and ranking down. It's harder and better now, global are globals and not silvers anymore.
