This page contains Full Length Freelancer Guides (at the bottom) and Mini-Guides.
This is an Index of mini-guides for every lancer. (A mini-guide is a few recommended builds and brief analysis — basically how to get started on the lancer.) The lancers are broken up into 7 separate posts (3 firepower, 2 frontline, 2 support), but the below links will direct you to precisely the lancer you are looking for.
If you want to Comment, here’s a link to a “Blog Post” Version of the Index where you can leave all kinds of general feedback on the builds.
