At the moment it's hard for me to tell what artifact is best to be at insane in long run. What is needed to play fast may continue to change as I accumulate a higher +AP%.
But with that Epic HB, Insane AcacheB, Rare TS, Leg SAC, do you have room to use a CB? I guess swap out HB when snagging a cache, and good if you have 4 slots. But if only 3, can't use both TS & SAC at same time, else no room for CB.
And what's with that Leg Idle Time? Or is it fallout fodder from the recent bundle?
