World of Warcraft Flexible Raids - Even More Noob Friendly?

As we all now, raids in World of Warcraft have been slowly nerfed for many years now. First the number of players required for a raid has been reduced to 25, which obviously made things easier for less experienced players who didn't know how to operate in large groups. Next we got Raid Finder allowing players with very little experience to beat all raid bosses even if a few of them are completely afk, but apparently, that's still not enough.

With the upcoming WoW patch 5.4 Blizzard is planning to implement new feature called Flexible Raids. The idea behind flexible raids is to allow a group of players (either guild mates, random people or Real I.D. friends) to party up in a group of 10-25 players and enter a raid placed somewhere between Raid Finder and Normal difficulty. Unlike in Raid Finder, players will have to invite others to the raid group by themselves.

Another significant change is the number of players needed for raid, in Flexible Raids your group won't have to be exactly 10 or exactly 25 players large - you can do it in 11, 14, 18, 22 number of players, or anywhere in between 10 and 25. Raid difficulty will be scaled automatically every time someone joins or leaves your party.

As Nethaera (author of the post) has announced, they want to give more social experience to the players, which basically means more chats in the middle of fights, more time to eat a sandwich, or even watch some TV during the raid.

So the question is, does this actually makes any sense? Players that are already slacking in raid finder, will slack even more, so wipes will most likely happen even in Flexible Raids. Players who are actually trying to contribute to the fight will only get more annoyed, which is also already happening in Random Raider. However, allowing people to continue a raid without having a full group might force people to try their best or they'll get kicked.

What do you think, are Flexible Raids completely useless idea, or does it actually makes some sense and might they be usable for casuals? Make sure to voice your opinion in comments below!
