Why would the Iroquois get a primitive special unit??
With only 25,000 citizens max divided over 5-6 tribes, it was a bit hard to built a lot of cities
. Nonetheless the Iroquois controlled a large empire (but mostly hunting grounds) for several centuries, and battled succesfully against the French and the British. If they hadn't made the mistake of siding with the British against the Americans, they could have grown enough to build plenty of large cities, and the Iroquois nation might have existed independently even today.
They are in the game because of their uniqueness (early democracy/confederacy and related social techs), geographic location (competitor to the Americans) and the fact that they were the only native tribe of significance that withstood imperialism, in fact they profited from it.
More obvious tribes to drop are IMHO the Zulus (for the Ethiopians) and the Persians (for the Arabs).
