What are you on about? You do realise that the very mechanics you are championing caused people not to run the group content? No one wants to spend an hour or more carrying out a task that they have no chance of completing through no fault of their own. When you get a situation where someone who does not know the fight is, more than likely, going to wipe the group unsurprisingly players do not want to group with them.
The only thing that need for CC takes away is the ability to use AOE skills killing one mob after another is not skilful.
