Well, there was a consistent shortage of tanks at the German spawn everytime I played. I actually joined the Russian side for a round thinking they were outnumbered, but took another look at the list and realized it was actually 17 Russian vs. 15 German. There were at least 6 to 8 tanks sitting in the Russian spawn, with 3 or 4 T-34/85s, several KVs and the rest T-34/76s or SU-76s.
Swithing to Germans to rebalance teams, I find a single Pz IVF/1 in the German spawn. That's just stupid.
I am also certain those numbers are exaggerated. Regardless, I played several rounds on the German side. I spawned once in the forward spawn, and there were only Pz IVs and StuGs, probably 8-10 total. The conditions for activating the German forward spawn are too difficult.
The team killing is a result of frustration from the unfair equipment assigned to the German team.
You will probably find the next spawn empty, as I did several times. See above regarding conditions for activating second German spawn being to difficult too meet. There are no tanks there at the beginning of the round, so if it never activates, there won't be any additional tanks.
The Russians, however, have an easier time getting their second spawn active early in the game. That's why I found the first Russian spawn full of unused tanks.
