Remove the dragons from level 7 (they are completely useless), increase the Harbingers to level 7, and place the Death Knights at level 6.

That would be a very good option! :)
Because dragons are completely useless :smile18:. And they're not even pretty.
It would also be great to replace the zombies with someone else :smile54:!
You can't even make decent cannon fodder out of them.

If you put the Death Knights at level 7 and the Knights at level 6, you'll get the opposite of HAVEN.

Actually, I would also change the color scheme of the Dark Knights. They are too much of an unmasculine color.
