Who would you prefer getting their hands on the mantle of Taken King?
Savathûn, Xivu Arath, or Toland?
Any of the three could yield disastrous results for humanity, but [u]which do you think humanity would have the best shot against[/u]? Please post your reasonings in the comments below.
No one else can take...
You could counter by saying that he wrote the secrets to taking beings on the tablet of ruin, except the in-game screwed up and used the tablet of ruin as a mechanic for the golgoroth fight, so if all that's required to Take things is reading the tablet of ruin, anyone who has beaten KF should be able to "take" people.
The only way to gain the power was to "take" it from Akka. When Auryx killed Akka, he gained the power to "take" and became Oryx.
It's safe to assume each proto worm has its own unique ability, Akkas was the ability to "take". If we see any new hive with special abilities, odds are we will find out they got them from a different proto worm.
