In the Patch:

Increase the warthogs upgrade prices up by 50%

Dont give covenant leader after temple is built, you would have to purchase it

Increase ODST price and recharge time

Decrease overall effectivness of super units, but still stronger than regular units

Increase damage of unique units, as i find the undeployed elephant pathetic

Increase spartan heath, decrease boarding time butlower damage

Thats all i can think of at the moment
