In the Karazhan 10 man raid the boss Attumen the Huntsman doesn't drop any loot. I've been doing this raid for a month now and every time I kill him he doesn't drop anything which makes it impossible to farm the mount Fiery Warhorse's Reins (https://tbc.wowhead.com/item=30480/fiery-warhorses-reins), Also there is no chess event so any loot from that is not available to the player.
