People did get carried. Hell, I know people that got carried. I never saw anyone buy them though. I'm not saying EVERYONE got carried, obviously.
Organizing a raid is a lot of work, I've been there. But at most, only 2 people do that. Everyone else just comes along and does their role. You cannot possibly be trying to tell me that everyone in the raid does the organizing.
Attunements were more an annoyance than anything else by the time you're in BT. Having to go back and run new people through all the time was a hindrance to progression.
At the end of the day, I'm fine with how they've done legendary this expansion. Sure, cloaks are kinda boring but they did cloaks because of how many people will be getting them. Quite frankly, legendaries are nothing special. Never have been. I play a game to enjoy myself, not place unrealistic importance on a virtual item.
