Is it me of is this normal?

After that fix update of WOTLK servers which contains alot of bugs in gunship/sindy/lk/bpc. I have noticed that Conqueror Marks didn't dropped for 3-4 weeks now in DBS & PP. Is this a part of the bug?

Alot of my guildies & members in a PUG raid always complains that Prot & Vanq always drops.
