Chestguard of the Fallen Hero - Magtheridon's Lair

Hello evebady. I have a smaller farming problem with this raid.
I don't know why, but there drop things out of BWL??!??
I have never seen drop ANY token for T4 EQ.
This is some warname-special april joke?
The Developers, Thank you in advance for your reply.

Maybe a bug. I think there's a 100% chance that one of the three possible tokens will drop?

Maybe it's a bug, they should drop. I've seen lately that some items have extremely low drop rate and that shouldn't be like that.
