I thought I'd share some of my rogue sites that I consult to get tips on the class.
www.roguespot.com -- excellent rogue discussion forum available here. You must register and apply for access to the Cloak and Dagger forum to get the most out of the site, as most of the good stuff is in that forum. Lots of helpful posts regarding talent specs for pve and pvp, maximizing dps, energy cycles, stealth runs, rogue farming spots... good stuff. Make sure to check out the link list to the left, too. Lots of good stuff there.
www.shadowpanther.net -- Excellent rogue gear list. Sorts rogue drops by relative value, allowing you to check out upgrades for a given slot. Different charts for PvE and PvP available. I used this to help me prioritize my upgrades.
www.worldofming.com -- Ming was one of the first GM's in the game, plays a human rogue on Lightning's Blade. His writing style will not appeal to many, but he offers solid, insightful info on the status of rogue pvp. Most of his content lately has been regarding his arena team. Check it out, if you don't like it, don't read it.
