Mythic+ Rating, Explained Properly

Mythic+ rating is the score that defines a season for most dungeon players, and the way it is calculated is widely misunderstood. People talk about it as if it were just "the highest key I timed," which is not how it works at all. Understanding the real formula changes how you should spend your week.

Rating is per dungeon, then summed

Your overall M+ rating is not a single number tracking your best run. It is the sum of a score earned in every dungeon in the season pool individually. Each dungeon contributes its own score based on your best run there. This is the most important and most ignored fact about the system: a player who pushes one dungeon to an extreme key while neglecting the rest will have a lower total rating than a player who runs every dungeon at a solid, consistent level. Breadth beats a single spike.

Timing vs. completing

Each run is scored on the key level and on whether you beat the timer. Completing a key over time still grants a reduced score — it is not zero, but it is well below a timed run of the same level. Beating the timer is worth a meaningful jump, and finishing with time to spare can push the key up in a way that beats a barely over-time run of a higher level. The practical consequence: a comfortably timed lower key is often worth more rating than a chaotic depleted higher one. Pushing the highest level you can barely survive is usually not the fastest way to raise your score.

Why your best run replaces, not stacks

For each dungeon, only your best-scoring run counts toward your rating; subsequent runs only help if they beat it. This means re-running a dungeon you already have a great score in does nothing for your rating unless you improve it. The efficient way to climb is to identify your weakest dungeons — the ones dragging your total down — and improve those, rather than farming the dungeon you are already comfortable in because it feels good.

Reading an M+ log

An M+ log on Warcraftlogs looks different from a raid log because the dungeon is one continuous segment of trash and bosses rather than discrete boss pulls. The single most important view is the trash, not the bosses: in most M+ dungeons the majority of damage, danger, and time is spent on trash packs and routing, while bosses are comparatively short. A player who parses well only on the boss pulls but contributes little to the pull-to-pull grind is not actually carrying the key.

Look at the timeline for the death and route shape: long gaps with no progress are wasted timer, deaths cost the group time and resources, and the deaths tab is even more punishing in M+ because there are no battle resurrections to spare freely. Time efficiency, not raw throughput, is the currency of a dungeon log. For how the two log types differ in detail, see Mythic+ vs. Raid: Reading the Log Differently.

How to actually raise your rating this week

Stop thinking "what is the highest key I can push" and start thinking "which dungeons are my lowest, and what is the highest level I can comfortably time there." Spread your runs across every dungeon, prioritize clean timed completions over risky depletes, and target your weakest dungeons for improvement. That is the strategy the scoring formula actually rewards, and it is very different from the one most players instinctively follow.
