Also.do you remember how easy you could have entered into a city in Morrowind?! There were open cities, not closed hubs. You were in Cyrodiil, the very seat of the Imperial Legion and of the Temple and there was no way to join them and quest for them. And, again it was kind of expected to exist. The Imperial Temple with their Nine - it was like non-existant. I've expected to see the Imperial Forts scattered all over the lands, but all i've got were ruins.
The factions were cut down in Oblivion, too.
In Morrowind, the Orcs were actually smart, the backbone of the Imperial Army. Gonna add the obvious involution of the Orcs in the series.
