This is probably one of those stupid questions I ask sometimes, so if you have an allergy to stupid you should stop right here and go read some Voltaire. I hear Voltaire is pretty smart.
Something that occurred to me last night about mutilate. Muti gives you +50% extra damage if the target is poisoned, so obviously you want the target poisoned all the time. I gather via skimming muti-related posts that people use Deadly Poison for this because it a) deals damage and b) can be used with Envenom.
That makes sense until I remembered that you need to be behind the target to use Mutilate at all. To get behind a target, you need to stun or incapacitate it, which is where I find issue; if you've got Deadly ticking on a mob to give your Mutilate extra damage, how the hell do you use Gouge to get behind it in order to Mutilate it?
Or do you just rely on KS and its 20 sec cooldown, giving you one or two Mutilates per fight given that you already have a few combo points built on the target from...something other than Mutilate? How do you build combo points for KS if you need KS in order to Mutilate in order to build combo points? If you have to open with CS to build combo points, what do you do with the Ambush that is available to you with your mandatory daggers? Does Ambush go off the action bar completely?
...or do you just use crips or something. I don't know. Like I said, this is probably a stupid question. It just seems to me like a really crap case of Mut not working well with every other ability you have.
