Ignorant question about spec order at Warcraft Logs
Right at the moment, I see Warcraft Logs showing affliction handily above the others at mythic difficulty. As you step down, demonology and destruction rise, affliction sinks. What causes that kind of thing? Is it a matter of better players getting more use out of affliction's potential, shifts because of gear scaling, something else?
It is far too early to draw conclusion from mythic. Just compare the amount of logs in mythic to those in heroic. You are going to see some screwy stats.
