I want to add my voice in as someone who Is very saddened and disappointed by the seeming afterthought communication by SE about the Diadem changes. I find it very sad they are removing current Diadem fully. I love Diadem but only have gotten to experience it recently as a new player to the game. Mostly I am very disappointed in the lack of notice that they were fully removing the achievements with only a few days for people to try to complete them (*almost* impossible to do).
