the main reason i use moxie is because of the moves i use, if your goal is a mixed sweeper, (i use fire blast, draco miss, dragon claw, and levitate magnet) you don't set up, and your goal is to do as much damage as possible as fast as possible.
and in the fairly common case that would get to the point at which outrage would confuse you, you have to sacrifice a fair ammount of power to garentee not killing yourself (refering to lum berry)
personally, salamece relies more on a fast-paced, aggresive presence, if you want to tank and sweep, use dnite. and scince when do you switch salamence on a poke that intimidate would make a huge difference? and on top of that, your opponent is almost gantureed to switch out to somethig that can handle mence anyway, intimidate is useful, it's just not salamence's style....
