Who's to blame here?
[1]Blizzard for developing such systems where it breeds toxic behaviour or the type of players that are in the WoW Community?
Scenario Case:
Mythic+ as a function is great idea. It produces replayability, may replace raiding to an extent, but the premade LFG system is a disaster. I now see people more speaking about the mythic+ situation, where you get declined for many hours at a time, leaving majority of players frustrated.
On the flip side I understand mythic+ key holders want a smooth/fast run, because it is too punshing if you fail, the cycle will continue, unless Blizzard decides to lesser the punishements, then people wouldn't care about success/failure ratio and decrease the decline ratio followed by increased Accept ratio in the LFG Premade tool.
Coming back to the point made in [1], who is to blame, at the end of the day?
