Hmm i don't think the mid game and early game are too short, i just think it is inevitable that a big team game goes to the end game (unless you end it fast). The longer the game goes, the bigger Axis advantago imo
the way i see it is most of your t1/t2 units with at abilities are for fighting off vehicles, light tanks, theyre effective when you have your infantry up against 1 or 2 vehicles.
in team games though you can pump out 4 tanks by the time you would pump out 1 tank in a 1v1. So that infantry guy who tosses an at nade and delays a tank and forces it to repair.. doesnt really do too much theres 3 more to come in and fuck everything up.
It's just a race to tech up, and theres only 1 tech timing push, which is the first team to bring a medium tank out can get some ground. After both teams atleast have medium tanks then its just kind of goes in to a very static tank off, which the axis usually win.
