Gargantuan (I just use it whenever it comes back on cooldown) and Spirit Walk/Fetish Army for the rest.
And yeah, Vision Quest is fun but since you're pretty much activating every cooldown you have whenver you can you sometimes get caught with your pants down, so to speak. As long as Spirit Walk is up I haven't had trouble running, though. My main problem with it is that it feels so clunky to just juggle cooldowns like that.
hmm interesting.
Some times I find myself needing to use sprit walk to run away (more than some times I admit) so i could use it in combination with that where I spam gargantuan + hex + soul harvest again then run away with spirit walk to recover everything quickly, then go back in for a full strength attack... but without the ability to soul harvest ..damn it
