There is no such thing as a legendary profile, anyone claiming such needs to go stand in a corner. Drops are all random, the only profile that *might* and don't quote me. Produce more legendary items, would be one that produces more item drops.
For instance... This profile runs through 200+ more mobs per hour... 200+ more mobs might = 200+ more items thus creating a better *chance* to drop a legendary item.
Hope this clears some things up...
Act 1, 2, and 4 have the highest density ratings currently... I've taken notice Act 3 and 4 drop more 63's then 1 and 2. But MP 1+ on 1 and 2 makes it possible for them too, to drop ilvl 63's.
