Mob Location / Secret Bosses Etc

I was wondering if an experience member of the 1000 Realm could give some Locations of Bosses and Where to kill out of area as opposed to waiting for them to spawn etc,

I know of King in STV , Doom in Dragonblight that is about it

thanks

Dooms are in, stormpeaks(use your stone), Pit of Saron(once in go to the right, there should be stairs on the - south- of the map) Forge of Souls(its at the end.)r check wowhead to find the instance if you need help there is also another doom but someone is always there killing it and its kinda hard to explain how to get there. KINGs: STV, and there wasss 2 in pit of saron but got deleted
