Well I have had one drop other than last bosses since the fix.
its been 35 complete heroics this expansion and I still haven't had a neck, chest, offhand or 2h drop whatsoever. I have done about a dozen half runs of just loot bosses, but they just never drop anything.
Its funny they created 8 int heroic necklaces in the table, but you just cant farm single items anymore because of personal loot. I think it is shit.
