I agree with Lava. Changing the build points is a false good idea.
Here is why : We all know SST...54 players, and a lot of BP. Some people likes it, others dont. Thats not the point. The point is we see some people who starts Trem in SST, stays in SST, learns to build in SST (with a huge amount of BP) and then one day they go to another server and try to build the way they did in SST. But they cant, because they got some bad habits with the high BP (such as turret/egg spamming, or building 2+ armories).
So modifying the BP for every game would only put chaos in construction, with the obligation to make new base layout for each situation and resulting in crappy base building most of the time
The current build point allow a quite good range of players around the estimated best which is 16 players (number of players for which the game was balanced, according to Timbo)
