Old thread but these forums seem pretty dead anyways, but I'm going to be rolling rogue here for the 7x event, and I'm mainly going to just mess around and do some pug raids when I can since I'm raiding as a Holy Paladin on another private server.
As for Pre-Raid BiS, this is what I came up with.
Helm: Darkmantle Cap - D2 Quest Chain
Neck: Mark of Fordring - Strat Quest
Shoulder: Truestrike Shoulders - Pyroguard, UBRS
Cloak: Earthweave Cloak - CC Friendly
Chest: Darkmantle Tunic - D2 Quest Chain
Bracer: Darkmantle Bracers - D2 Quest Chain
Gloves: Primal Batskin Gloves - Crafted
Belt: Mugger's Belt - Kromcrush, DM N
Legs: Plaguehound Leggings - Strat BoE
Boots: Darkmantle Boots - D2 Quest Chain
Ring1: Don Julio's Band - AV Exalted
Ring2: Might of Cenarius - CC Revered
Trinket1: Hand of Justice - Emperor, BRD
Trinket2: Earthstrike - CC Exalted
MH: The Lobotomizer - AV Exalted
OH: Bonescraper - Rivendare, Strat UD // Distracting Dagger - Tortheldrin, DM W
Obviously some of these aren't available until the War Effort, but I'll be taking my time gearing anyways. I'm also going to be playing Daggers instead of Swords for a few reasons, mostly that gear competition with Warriors is significantly decreased by playing Daggers, and I like them more for PvP. I also am sick of playing Human, so I'll be playing Night Elf, which happens to be the best race for Dagger Rogues thanks to their heightened base Agility. I'll be playing around with the Darkmantle 4-Set, and if I don't like it, I'll swap some pieces around. The chest will be staying put, though.
EDIT: The other server I'm playing on doesn't have Librams, and since I play a Holy Paladin, I completely forgot about the ranged slot. Satyr's Bow from DM E would be pre-raid BiS.
