What a builder needs is time one his hands :P I don't know if it's just me, but it takes me a long time to write a build and even longer to play test.
What you need to make a good build is dedication. It requires you to play test and work out game mechanics to play with. Although every mechanic has been seen that cannot stop you from being creative with your build. Mixing in role play and lore with the build is also good to have. And of course artwork! Artwork makes a build so much better to read and gives a overall better look to the build.
