A great way of starting a discussion Here is a rating , this is the absolute truth , I am not going to respond ! First There are 20 parses . Any data generated from 20 parses has no statistical significance whatsoever . Claiming an aggregate data set of 20 parses can be considered valid without needing explanation is very silly and proves a complete lack of understanding of what these numbers actually mean . Try the EN rankings , at least there you get a few thousand parses . Second The tank survivability rating has been criticised a lot for not being overly accurate and having plenty of shortcomings . Placing that here as the one and only correct answer is simply ridiculous . <| sep |> It used to be more open . It is less open right now because they ' ve added more rocks . The biggest issue is that they need to keep some land open to allow room for more rad towns and stuff like that .
