Hello. I'm considerably new to the rogue class and so far I have only tried playing Combat in PVE and Subtlety in PVP, so please forgive me my ignorance. My question is regarding Assassination and how should I perform in, say, dungeon/raid trash or multiple targets in general. I know trash isn't important, but getting through it faster is always a bonus and currently I don't 'feel at home' if you will.
I mean, when coming from Combat background, you are so used to just cleaving stuff to death. Now, I do know that Mutilate is the rogue spec when it comes to dealing AOE damage, but how should I do it? Let's say I'm faced with 3-5 targets. On how many targets should I keep Rupture up on? Should I then just keep doing a single-target rotation? At which point there's enough targets to keep spamming FoK?
Thank you in advance for whatever help.
