It has been mentioned by sul'dam who have leashed a Aes Sedai that they are useless in battle. I can't recall the exact context (after Falme or in more recent books, beats me) but I am certain the Oaths still prevent usage of the OP as a weapon when collared.
Also the art of linking has been lost in Seanchan because all Aes Sedai who knew about it were leashed. And I doubt they will allow a damane to link with another. who knows what it would do with the suldam and all the emotions they recieve... (if of course they CAN link when collared)
