The imperfect transfer clearly shows that you lose some stars and sancs, but it also reduces your previously gold sancs into white and blues? I had a half angel V with mainly gold sancs that now have mainly white sancs. That's a pretty steep reduction. I think this makes the transfer almost useless unless you were transferring lots of stars. For purple heroes, you could easily get spirit for 4-5 cards that would give you better results than the transfer.
