New building and New units orcs!!!

I have an interesting idea for this game and add my favorite race of orcs is
They can have their own special buildings and trained army of orcs from this building

I have some idea for type of the orcs units :

warriors : HP 500- Damage 45 per sec-Ability none

wise old man : HP 180- Damage 28 per sec-ability haste give bonus attack speed to all range units in small area

in the future i will add more units plz help me with your comments

good luck

I agree with adding a Orc unit but they shouldn't have their own special building it should be a new dark troop
