While i certainly like the extra difficulty, and i believe we can all agree that they nailed it just right with this new raid, i have a few doubts whether or not this is a viable approach for the long run.

My concerns by running a few runs of weeping city are:

1)Most people have the mindset of going in 24man raids for a chilled run, hell half of the people are semi afk or don't use all their skills. The fault here is solely with SE making all previous 24 man raids a faceroll, for example Void Ark.
2)People don't focus on tactics, they just avoid the basic stuff and dps, introduce the slightest of tactics such as ozma meteors and wipes occur.
3)The raid timer is not friendly for learning groups, my experience is that by the time everyone understands tactics and you can progress, you will run out of time, making the whole run a waste, since you cant just re-apply with the same people.
4)People that know tactics have a short temper and will either rage-quit or spam Vote Abandon with every wipe. If a tank or healer leaves good luck getting a replacement before time runs out.
