I think the raid is brilliant and sets a good and wild precedent for the remaining 24-mans of this expansion.

Yes, there is a big learning curve, but I do not think the curve is unreasonable. The raid will also get much easier over time thanks to gear creep and thanks to veterans learning all of the tells.

Until then, it's nice to have a raid that has teeth. Even once gear creep rears in 7.2, it will require more focus to survive.
