UUs are not comparable to regional units because they are made from a castle or require a castle to make or are part of a team bonus. The building of a castle or multiple castle is often the bottleneck to creating UUs such as the longbow or Keshik or other units which are comparable to other units
You know for a thread asking if Huns and Turks should get steppe lancers, we really got off track and discussed whether the Persians should get steppe lancers Lol. For my part I am sorry lol.
