So the cah orc/uruk classes have gotten pretty outdated compared to other races.
Here i have a few suggestions on what to add
Uruk
-Ability to ride a larger Isengard warg
-Reinforcements summons Isengard units instead of Mordor orcs,
Scouts at level 1, and then more advanced troops later, highest level also a berserk
-New armors

Orc
-Gets a new model, because no one uses the current one..
Model would be same as The Defiler
-Reinforcements summons Dol Guldur orcs instead of Mordor ones, and more at higher levels, at the higest even a guldur troll
-Ability to ride a Huge Gundabad warg
Armors
-Azogs Movie armor
-Bolgs movie armor
-No armor
Helmets
-Azogs normal look
-Bolgs movie look

Weapon
-Azogs or Bolgs club or a sword
-And you can choose between a sword hand, grip hand(like in earlier movies) or just a regular one:D
