But what is late game exactly? In 3 right now, every one pretty much has access to some sort of armor (besides UKF), relatively early compared to 1 and 2. Thing is in vCoH and CoH2, besides few light tanks there was no armor awaible early\mid game what so ever, while in 3 there are plenty of it relatively early. So it should be clarified what is a late game to begin with.
If the game is not completely one sided in 3, you always reach its late game anyway, with a difference being that in other games lategame comes at around ~20 min mark and in 3 its around ~15 mins.
As of Right now past the 15 min mark, I' can't speak about 3's but then again I believe the game is balance around 1's and 2's.
That's Kind of of the point of the larger windows in of early and mid, so instead of everyone rushing to late tech to get the first tank, which only really gives you a 2 or 3 min head start on contrary to coh 1 infantry and light vehicle play is very impactful and deadly. The dev diary's themselves said they took a lot of inspiration from coh1 and even old veteran players like me could tell that coh 3 is heavily based on coh 1 WITH sprinkles of coh 2. (the good bits).
