As someone who is not a mythic raider, I absolutly love this change.
I love running M+ but my guild is far from mythic raiding so atleast 4 of my slots are filled with 915 gear, while the rest is 930+.
Also the class distribution within the tokens was TERRIBLE.. Mage+Rogue+Druid+DK mixed into the Vanquisher token was just horrible.
With titanforging gone for the Azurite slots, mythic raiders and high M+ groups should be good with this change.
