The What’s Next panel brought some Mythic+ news as well. In addition to the Season 3 dungeon roster, we got word on some new rewards and changes to how the top percentiles are calculated!
There’s a new top 5% reward for Mythic+ rating, in addition to the current ones.
On top of that, the percentages will now be calculated against players of your spec, not all players. This is only for the 1% and 5% rewards. It adds a lot to the “play what you want to play” philosophy and Blizzard hope to see a lot of spec diversity in Season 3.

Here’s the official post explaining it all:
Push your limits, climb the rankings, and earn new seasonal rewards based on your specialization.
Season 3 brings new goals for Mythic+ players, including an additional reward tier for the top 5% of players and updated eligibility for both the top 1% and top 5% seasonal rewards.
Players who finish Season 3 in the top 5% of Mythic+ ratings will earn a new seasonal reward. This new tier gives more high-performing dungeon runners a chance to show off their accomplishments each season.
Beginning with Season 3, top 1% and top 5% Mythic+ rewards will be awarded based on your ranking within your specialization instead of your overall ranking among all Mythic+ players.
For example, if you push Mythic+ as a Protection Warrior, your eligibility will be determined by how your rating compares to other Protection Warriors. The same applies to every specialization participating in Mythic+ during the season.
Gather your group, choose your specialization, and prepare to climb the Mythic+ rankings when Season 3 begins.
