If you at first make your normal Scope-proc go on CD, then 10 sec after use aMoC(with Scope buff not on) and then auto shot the dummy all the time, Scope should proc a bit later and you see the sudden 1k/tick damage jump. This is why you SHOULD use it outside of BW, because it only gets ~half the benefit of the 10% increase of BW(So 5%) where an Arcane Shot gets the full 10% increase.
Edit:-----
Go test this on Dummy, use aMoC without any procs, then Midway, use your BW(along with: Blood Fury(if Orc), Engi Tinker(If Engi, hopefully yes) and maybe potion). You will see the damage jump.
