Hey all, i just did another instance, Blood Furnace.
Super easy, much easier than Slave Pens.
The only trash mobs that were issues were the technicians that drop the mines. Just kill em first and they shouldn't be an issue.
Broggok event thingo with the waves of mobs caused me about 3 wipes, till i remembered i can fear bomb.
I know these fights seemed unrefined, that's cuz they are, they're my first runs into each instance as a 5 lock group.

Description: The easiest and quickest boss, very straight forward. Just DPS

Broggok
http://www.vimeo.com/1247629
Description: This has the event where you get groups of mobs come at u. I wiped 2 or 3 times before i realised i had fear. Just fear bomb and kill off. Keep the last one feared so u can bandage up before the boss pull.

Description: Last boss, use shadow ward, that debuff sucks, next time i'm waiting out the 2 minutes and keeping one of the mobs feared. Alternatively, bring a felhunter to dispel it.
