T34/85 can easily take a p4, not to mention u get 2 out at a time. Plus the fact that a soviet player can have 2 T34's on the field b4 2 P4's can be made. So if your lucky as a german player your first P4 will stay alive untill reinforcing armour arrives.
The main problem with the game at the moment is that once a soviet player gets dug in it's very hard for a german player to advance. I'm jst thinking of ways to make the game abit more back and forth.
Panzer IV has the armor advantage over t34/85, as well as raw DPS. The Panzer IV reloads in 6 seconds, the T34/85 in 8.7.
Panzer IV will kill a t34/85 in 28.07 seconds.
T34/85 will kill a Panzer IV in 42.17 seconds.
Panzer IV vs t34/76 from the front is not worth mentioning. A soviet player cannot have 2 t34/85 before a german player gets a IV out, unless the German player is heavily losing.
Brummbar is currently overpriced, this is not new.
If you win 75% of your games you have not played enough for your ELO to go high enough to get more skilled matchmaking.
