Now it is. It wasn’t before the buffs.
For a reference point: here’s what Algalon representation looked like pre-buffs
(The percentages were determined by taking total Algalon kills divided by total parses of that spec in Ulduar at that time)
Ret was right around arms warrior in relative (and total) representation. It was FAR from wanted.
Ret was being sat for hard content. It wasn’t a good spec. That’s why it got buffed.
