People have you actually read what the topic creator wrote ???

Apparently no !!!

He made it quite clear that he no longer enjoys dragging trolls behind him all the time to kill them.
He would like an alternative way to defend a base in a different way and I can only agree with that here.

Trolls are killed in the same way over and over again, either I run away and drag them behind me, or I go to an indestructible point on the map where trolls cannot reach me and kill them there.

That gets boring in the long run.

And the fact that he lost his wolves is because he brought them exactly at the time when the attack on his base took place. You can't just get everything out of the way and then comfortably attract the anger of the trolls.
