What is the lowest raid lvl? Right now im lvl 53 and bord of ST and never exspeced in BRD and i dont even think about LBRS so what lvlis the lowest raid? I really want to know to get some better gear for Outland.

Honestly, you're going to update all your gear at lvl 58 when you go to the Outlands anyway.  My suggestion is to run BRD and the Spire till 58.  You might as well do the attunment quest chain for Oxynia (spelling) as that will take a forever (at 70 i still haven't done it).

They both have great gear with Tier 1 dungeon sets that drop for big $. 

Good Luck. 

60 raids are kinda obsolete now, unless theres a large group of people who are either bored and dont have BC expansion. i think MC is gonna be upgraded to an 80 raid
