You're welcome... the skins fit in much better, right?
Also some unit suggestions...
Warg Rider[Uruk Hais](this): Fast unit, can do hit and run tatics, has the Run(increase movespeed, base it off berserk or Grenzy) ability
Runecaster[Dwarves](This): Good spellcaster, effective at support, can cast Stone Rune(Inner Fire based, increases armor), Fire rune(Incinerate arrow based, gives bonus damage to the runecaster) and Water Rune(Heal Based, heals)
