It's been 2 weeks and Valithria is still bugged

I'm sure it's been reported by dozens of people in the bugtracker, and considering nothing has been done I am creating this threat to attract a bit more serious attention on this issue.
The adds on the Valithria 25 NM encounter have been spawning really slow for 2-3 weeks now, giving people basically free items. I mean, the boss was easy before, but now with this bug it's literally free loot. Please do something and fix her asap.

It's weird but it's as if on every maintenance 2 bugs are fixed and 3 new bugs appear. I have no idea what is going on.

Valithria has a common bug where the beginning adds multiply and you must change heroic/normal or vice versa, in order to remove duplicates.
