hellom im playing from Lithuania nordics. and I have huge lag spikes ping jumping to 200ms huge studders in game and i shoot as mcree its kinda double shoots sometimes. its clearly server issue… i used to have nice and steady 40-50ms ping for 2 years. For couple month not game star to be unplayable, today i have 80ms base ping its not normal, im not playing from australia, i have 300mbs fiberoptic connection, for other games i have low latency like 14-30ms. Blizz pls fix this ASSAP or return my money.
