Why wasn a system for creating our own character templates included with the rules, ala West Ends Star Wars game?
The lack of a build system is not an accident. The types were created and balanced against one another not according to some over arcing numerical system, but through a) eyeballing and b) play testing. In order to create solid types through eyeballing it, Robin D. Laws suggests playing for a while and getting familiar with the system, then applying common sense. Not any kind of numerical rules system; these can always be hosed.
