It’s not really irritating to me, it’s just pointless. “I don’t have any evidence, but my blah blah got rivered by a yadda yadda, so the RNG is unfair.” What is that sort of thing supposed to accomplish?
Are the devs going to say, “We seem to be suffering from the dreaded Y2 Blah Blah Yadda Yadda Bug! We better devote all of our resources to finding a fix ASAP!” The devs either rigged it and don’t want to fix it or they know it’s not rigged and doesn’t need fixing. Either way, it’s not getting changed, so what’s the point?
Bingo players don’t have the skill to play any other way, and most probably think skill isn’t a factor. Will complaining change the way they play? If you can’t beat someone who has no skill, maybe your time would be better spent putting your own house in order.
The endless avalanche of complaints isn’t irritating, it’s just pointless in most cases. It can never and will never make any meaningful changes occur, yet it goes on and on and on. “Tedious” is the right word.
