MW has been great for a long time, they just get overlooked because World First guilds don't use them on progression because they 100% need DR cds to survive mechanics at lower gear levels, and everyone else follows the trend. 99% of guilds can effectively use a MW and clear all content because they aren't restricted by the same things as World First guilds. The same goes for Rdruid and Hpriest. Unfortunately meta shifts wont happen unless DR gets addressed or the throughput of Hpriest/MW/Rdruid is so significantly far ahead of Disc and Hpal.
Or you just read the info and accept that if you can play pretty much what you want, which is a good thing? I think it's a good thing anyway...
