It looks like you're new and since the raids are new to you there's no reason to hate them. For me the reason I can't stand it is that they ignore the old raids as soon as a new one comes out making the old raids obsolete. So you end up only playing the new raid because the old raids are worthless for gear and advancement. Then they make the newest raid the only way to get to the highest light level so you're forced to run it over and over and over without playing any other aspects of the game because they become worthless for gear and advancement. The raid itself is ok and on normal it's not a pain in the ass when someone makes an error and dies because you don't have to wipe. If you played hard kings fall 3X a week for four hours per raid like most people had to back when it came out, you'd hate it too.
