How about the point where the game is
having greed as its only purpose to exist by the developers which abandoned everything else about it
swarmed with cheaters financed and sanctioned by state actors for propaganda purposes, with nothing happening to reports
changed arbitrarily so some nations perform unrealistically better than others, with no willingness of Gaijin to improve balance
staying completely unchanged in core mechanisms while new additions for sale's sakes just break more and more stuff without fixes
becoming a farce, where even the earlier promise of improvements and potential fade in the face of blatant P2W cash cows on broken maps, with broken pretty much everything.
