Dungeon​ Bosses not dropping Loot

[Yunix]

I was doing a Sunken Temple with some guildies yesterday and only one of the bosses​ dropped loot. (One of the Troll Minibosses). No other boss dropped loot at all just some silver and cloth scraps. I've also noticed this in numerous dungeons like Zul'Farrak, Shadowfang Keep, Scarlet Monastery, Razorfen Kraul and Downs and some others. Is this blizzlike and/or intended?

Happened Again in Sunken Temple. Killed the Last boss and literally all the group got was 2 silver. Is this for legit though, a bug or is this blizzlike?

Happened in Shadowfang Keep multiple times with the fourth boss, Commander Springvale, he hasn't dropped anything, except a few silver and some wool cloth.
