I'm with you, but I think we should just multiply all costs by 2. Therefore, when you put points into Warfare, you can then spend those points on subtrees that cost 2, 3, and 4 (instead of 1, 1.5 and 2). I figure we'd also double the points we'd get; this would just be to avoid spending 1.5 points on some trees.
