I couldn't but grin about this comment.
I don't really understand how they claim to trust sources like simcraft and logs as much as their internal sources.
A fast view of the logs at the moment speaks the truth : 82 ret paladin parses on mythic kj fights last 2 weeks when more than 150 guilds have killed it...
The same spec that has one of the largest number of parses on first bosses + a notorious history of cheesing and soaking mechanics with their damage reduction and bubbles is underperforming in an instance with a gazillion of soaking going around and climaxing to the last bosses.
But what do we know . Maybe rets are normies these days.
I hope they cut the bs and fix the balance problems.
PS: my "/yell wheelchair coming through" macro when moving around to deal with mechanics is the most popular thing i bring in a raid.
