Whiteball is a nicely designed map. I much rather play on redball than Port of hamburge.
Even though this is completely off-topic and has nothing to do with Chaos Krieg I have do disagree with Whiteball Express being a very good map.
I feel like the map is certainly above average compared to the other 3v3 and 4v4 maps but at the same time I don't really enjoy playing it because it is too open and too easy for team weapons.
Most of all the huge stone church at the middle VP is HORRIBLE as it becomes almost completely undestructible for OKW facing Soviet Urban Defense. The houses north and south of the central VP also promote very safe forward HQ gameplay which is again annoying.
Apart from that Whiteball express just favours UKF and Ostheer too much because of how dominant MGs and long-range infantry is IMO. The map would be better if it had a few more sight and shot blockers on the left side of the map and if the church was set to only 50% HP or even better if it was completely destroyed. Anyway that is my personal opinion of it.
