H-Hour, I looked @ the latest versions of the (simplified) columns & have to tell you honestly that they really do not look half as good as the old ones...
The massive design of the old ones looked much better imho...
You should not really care too much about the compiling times of your map as the gamer will not have to compile the map anyway, like Kildor already mentioned & I am really wondering why Duke with the fastest computer around here shouts so often & so loud & makes you change your great design
...
You rather should take care of short loading times in-game. This can be achieved in many ways & can be optimized & applied @ a later stage of development of your map also, but do not sacrifice visual quality for shorter compilation times...
