Well you guys clearly didnt read the new concept..
And a little rude, but honest, the way it should be:)
But as stated in the concept the leader hero is a replacement for Gothmog. Not a new hero for gameplay, as you choose in the beginning if you want a Morgul themed faction or Dol Guldur themed. And as stated several time, he is not Azog, nor the Defiler from MM. So "Azog" is not in two different factions.
And the great thing about nameless heroes, is that they arent non canon. I mean there probably was some orc leader in Dol Guldur, yould be suprised how many leaders it takes to control an army for real.
The same way the Witch King is leader of Morgul and Gothmog is his General, it would be like with this guy and Khamul. Since neither Khamul or Witch king tends to have leadership abilities, heros like "Gothmog" or "The General of Dol Guldur" in the concept step in.
And as i stated in the beginning, i dont expect for this to happen anytime soon (or ever) but it would be nice to see in the game. So you dont have to worry;D
And please read the new concept before commenting.
There you will see it includes no new units for when you want to play the classical Morgul oriented Mordor. But when you want a more hobbit feel, this would be a pretty great concept without tons of work or change to the game as it is now.
And you say all of it is unecessary, sure it is if you just want to play the classical Morgul oriented Mordor, but if there was the ability to chose between also a Dol Guldur oriented Mordor, it would be the best way to include all the good hobbit designs without making alot of people unhappy, and it would certainly make all the botfa Dol Guldur army lovers really happy. And shut them up about the Hobbit evil army.. or atleast me:DD
