Well if you don’t do that then the season is basically over for a lot of people, people can’t push keys to the highs seen in the first 2 weeks of 10.1.5, and the 0.1% title spots are inflated into the realms of keys that even good specs (But not god comp) cannot compete in. You still need a priest for every title range HoI and Uldaman, you still probably need one for every title range Brackenhide.
The changes as they stand do not foster diversity or competition. They just stop things getting any worse.
