Rupture - Keep At-least a 1 CP Rupture Up on a Rogue throughout, non-stop, once you’re about to kill one, be sure to rupture before you try to finish, otherwise a vanish can just ruin you!
Eviscerate - use on cloth wearers, casters!, and when you’re trying to do some burst, works great with ShS - Evis. Crits hard even through 300+ Resil.
Envenom - Yeah I named my rogue after one of the *worst* finishers out there, but i like the word! =P. Uhm, You’d NEVER use this in arena, about 99.999% sure of this. Unless You’re Crazy!
Kidney Shot - I always love to use KS right after a trinketed blind, I would blind my target, and wait for them to trinket, so they walk right into a 5CP KS. if they don’t trinket, then you get to open up on them again, go downtown to chinatown on their ass!
Expose Armor - I Almost always open with this move, basically your damage output increases dramatically through armor reduction, and thus, you hit harder! Horray!
Slice And Dice - I Always hit SnD when i hit 100 energy and i am facing a mage who has just ice blocked, so i might as well spend my energy somewhere!, always get the energy bar addon, so you know when you’re +20 energy will tick back in!. if not, counting to 3 is quite challenging when you have to multitask immensely!

I Think I’ve covered everything..Yeah!
