Well, it didn't sound that way.



What he said concerned mostly the efforts to secure a soul (which isn't an issue if this was done at SG) and that the DO wouldn't expand those just for anyone. RJ never said the act of transmigration itself is difficult to the DO, he never made any comment on that.



Do I really need to explain how this would be really different from stripping her of everything she held dear except her life? If the DO wanted Mierin to be ugly, he would have disfigured Cyndane's body. That was not the object of the punishment, the goal appears to have been to deprive her of everything "Lanfear". He "remade" her into a girlish bimbo, gave her a true scorn name this time, not one that flatters her ego (she's the only Forsaken to have chosen her own before people granted her one - (or in fear they would no consider her nearly as frightening or important as she wished), and forced her to be a servant who can't even decide how she dresses or where she goes.

What's more plausible as an alternative that Moridin had to pay to get Lanfear back by letting the Finns kill her (they would have been far more likely to ask for more of her strength before they give her back than for her death...) is the slim possibility Lanfear managed to kill herself before reaching SG (but it's a very slim possibility, Lanfear would have known that was no solution to escape the DO, and she doesn't seem the type to commit suicide anyway). For the rest, I really doubt Moridin didn't know how to properly make deals with the Finns, he's not Mat.
