Try weapon upgrades, usf nades, 5th man.
What do axis have again even for basic resource management or decision for tech vs upgrade?
You make this again to be a "axis vs allies" thread when it has nothing to do with that. Every faction could use more upgrade abilities. Brits has the most currently but could easily have double the price and increased effectiveness to their upgrades to really make them game changers.
But i guess the most complicated RTS you have ever played is probably DoW2 so i don't think you will ever understand....
Unless you have obtained master league 1v1 in sc2, please don't even bother to respond because you have never been high level enough in a strategy game with depth to being able to comprehend this.
