Atm my rogue is equiped with mixed gear to get the balance between dmg and health. Thats perfect for funny WSG's.
But I'm working on dmg gear - that means same gear but only agi gems and ap, agi enchants so the crits become more and more amazing
In general you should go farming items with max socket slots in regard to Cataclysm when new gems are introduced. At the moment some wotlk quest rewards without sockets have better stats than "weaker bc-items" with sockets. The new gems come with 40!!! agi wtf and if there is no change of restriction we can use them.
Iroared presented some really good ideas like his offhand or waist.
And if you are lucky with the auction house then try to get a 69 waist, thrown-weapon and rings with "of the bandit" stats for BiS and better than all quest rewards.
Engineering is must have but your second profession is your choice. I prefer Blacksmithing cause with Cata-gems it brings the double amount of stats by other professions. Pre 4.01 Herbalism was found on many twinks through all brackets but has been nerfed hard so that the heal effect is reduced to 1/3 of the previous amount. On the other side they added a 20% haste effect for 20sek that you do not really need as a rogue whose strength lies in hard openers.
Remember that you are able to put an additional "enchanting-enchant" on your items that only had an engineering enchant before 4.01 e.g. ZG head enchant (make quick, in 3 weeks it will be removed!), shadow armor on cloak, tuskars on boots etc. Oh and if you want your rogue becoming perfect get also ZG shoulder enchant - I might remember that it has 5 additional ap (not sure but nearly 5) as the Aldor one that is acivated at level 65. You need exalted with Zandalar tribe with your 69 to get it for Cured Mammoth Hide Mantle (BiS shoulders). Hurry up ^^
a chardev profile will follow soonly ;-)
