I have mixed feelings about the raid.
From personal side the fights have really boring moments and really fun moments the first few times..Like Opulence and gems is fun, but the mini bosses is ZzzZZzZZ, Mekkatorque is fun and generally maybe apart from the first boss the rest all have their fun moments and their "oh shit i have to play" moments but..
From a casual HC guild raid leader of few good players and a few half-decent ones, BoD is a nightmare because 100% personal mechanics to people that raid last few years with babysitting everything for them its A NIGHTMARE.
Their mentality with some bosses lately of 100% personal and communication mechanics is not liked at all.
You cant ask someone you raided with the last 5 years mute to suddenly start speaking..Or the person that cant because gf went to bed etc.
