Sorry Yoshi, but if you award the best weapon in the game by winning the lottery...

People didn't complain because people knew relic would be another option in time... People had a choice of doing the raid and getting a 275 early or using time knowing down the road they will have a 275 which is fine in my book giving a higher ilvl them both of those by RNG linked to bad content isn't okay in my book especially when the rng is so low that only a few will get it even those who don't really deserve it compared to people who spent majority of their time working hard on relic or the raid. There is only one place to get a 280 weapon and that is diadem which is the only option to get it and that's what people hate and making it RNG just adds salt to the wound when you can just afk waiting for emergency mission and then potentially get a 280 with hardly any effort.

Also even though the ilvl is 280 it actually has the stats of a 285 and potentially strong as a 290. It's clear that without the 280 weapon diadem can't stand on it own legs which is another flaw in its design. They knew they made it terrible so they put a weapon in there to get people doing it when the content is just bad.
