I recently decided my Nurgle Daemon Army needed more punch so acquired some Blight Kings.

At a pinch, they could also serve as Nurgle terminators, assuming I ever play 40K again.

I like these models: they are full of character.

Of course that rather depends whether the next edition of 40K cleans it up and turns it back into a playable Fire and Manoeuvre wargame as opposed to a bloated monster.
