"Apart from the people who disagree with me because they are biased, everybody agrees with me"
Just the pro players.
Now as far as the game goes if you don't have respective tank force when ISU arrives I dare to say that you've lost this game long before this happens.
The game that I played that made me so passionate about this issue was going my way all day until the ISU hit the field... at which point my army evaporated. Did you see the game that got Hans so upset earlier today? It was neck-and-neck vs. cruzz, right up until the ISU hit the field. At that exact moment, he had the strategic initiative.
On a more general note, there is an enormous difference between 1-shotting a squad and 2-shotting a squad.
