the MMR system is flawed
ive been able to luck master on a smurf while floating around D3 on my main, +30 for a win -7 for a lose with double promotes and series skipping... the elo system was perfect with +14 +13 +12 +11.
all the MMR system does is overrate people or keep you guessing if your mmr is good while being trolled in your series. need 18 LP for series? fuck you your getting +17. ranked begins at master tier where you actualy get normal gains..
