I have just read a preview article on PCgamesn website and I got a little confused. How will the phases exactly work?
The overview in article says that the first 10 mins will be infantry only, then some tanks for another 10 mins and heavy tanks only afterwards. Article also states that this phasing is realistic.
I have my doubts, which I would love to have dispelled on these forums

In gameplay terms: Why is there going to be a limitation on player freedom? Considering the balancing track record with Wargame series, are you guys confident that adding another factor (selection which phase can the unit come onto field) is a good idea, which will not make balance even harder to achieve? Will the size of the map change during the battle, or will I have to cover most ground initially with the slowest unit type?
In realistic terms: I might be wrong, but from what i've read the most common engagement type in WWII was a combined arms (infantry supported by vehicles) unit running (on purpose or accidentally) into enemy fortified position. I don't remember reading about many battles that started with an infantry clash that escalated into a large battle.
If there is offense taken, please blame my English skills. I don't mean to offend, I am only curious about the new great thing to come out of Eugene.
