Would I have a ranged weapon, unlimited ammo, and plenty of room to run? If that's the case I'd take on the dwarf midgets. On the other hand, a mile high giant who's only a third that high would be a better option if I'm using melee.
I've got the image of tiny, bearded men trying to run but scuttling along like one of those overweight dachshunds.
What if you had a trebuchet and a mancatcher?
One hundred tiny, bearded men launching into the air. "Fly and be free little ones!"
The midget giant scrambles to catch as many as it can in its mouth because its arms are too short to feed itself. Soooo hungry.
Is a giant midget just a normal-sized person but of midget proportions?
