Morgoth is the only Maniac who at least sometimes succeeds in convincing Grarmoth, the team´s leader and owner, of some strategic plan that Grarmoth didn´t create himself.
Wether or not this is because Morgoth being his cousin is not known, but he actually managed to persuade Grarmoth of not buying more than the two actual chaos dwarf players,
"To keep up a speed that almost every other CD team loses when they field so many slow blockers."
Of course it´s just a rumor that the only reason for this tactic is the traditional post-game poker session, where every player except for Morgoth gambles away his income, and that Hobgoblins are much worse poker players than dwarves of any kind.
