Grades on the night: A- 87.3, A- 86.6, B+ 83.7, A- 86.0. That is about as flat as this tool gets.
The damage axis was 44, 23, 35 and 46 — mean 37, and by a wide margin the lowest thing on his sheet. It is 12% of his grade and it is the only reason his letters are not higher. Here is why it should not be read as a fault.
The axis measures his damage as a share of the party average, on a band where 36% scores zero and 80% scores full marks. His shares tonight were 0.555, 0.461, 0.515, 0.564. That band was cut when this corpus was almost entirely him in +2 to +9 keys, where his own median share was 0.670, and it has not been re-cut since.
What actually changed is the denominator, not him:
his dps share implied party avg
18-19 Aug, ilvl ~283 74,507 0.678 112,344
28 Aug, ilvl ~311 100,415 0.535 193,075
His own output is up 35%. The damage dealers around him are up 72%. A tank's damage scales with his gear; a damage dealer's scales with gear and with bigger pulls and longer fights at higher keys. The share had to fall.
The control that settles it, across all 46 archived keys, at +11 and above:
Doryhunky Veng DH median share 0.552 (n=14)
A Prot Paladin Prot Paladin 0.554
A Fury Warrior Prot Warrior 0.554
A Blood DK Blood DK 0.761
A Blood DK Blood DK 0.760
The two non-Death-Knight tanks land on his number to three decimals. The two Blood DKs are twenty points clear of all three. That is four tank-keys of control, so it is suggestive rather than settled, and each of those keys was a different group — but it points at spec and content, not at effort.
What is real on his sheet is interrupts: 79, 83, 80, 69, mean 78. He is the single largest source of stops in every key of the night (22, 24, 33 and 21 kicks, plus crowd control), and the axis still reads slightly under the share his position and uptime predict, because a tank is in every pack from the first second. Temple of Sethraliss, at 69, is the one to look at.
