If you had been on PTR on the latest build, you would have seen that they actually have over 3k stats 940ilvl. It was only a placeholder until they put the real value for them so they have the same value as another 940 ring would have on top of the talent it gives.
Making it class campaign and balancing the raid around the fact that everyone would have that ring would have made so many more people happy than how they are making it now. They are already adding 1 legos for every spec on top of the ring.... no need for more carrot over 99% of the playerbase doesn't have all their legendaries yet so we have plenty of carry to chase after already.
