Some very strange paragons to take. Some people enjoy actual meaningful combat.
Anyway, I'd say the basic beginner advice is the same as with other art form: make sure you learn all the rules before breaking them. Make a few nice looking techbases where everything is perfectly aligned, combat is serviceable and pleasant, geometry is mostly orthogonal, and so on. Then, once you can make stuff like that with both eyes closed, decide on your own which rules are worth keeping, and which worth breaking, with a slant on the latter if appropriate.
