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.
LINKS TO OTHER RECOMMENDED GUIDES
Here are some guides that others have written that I think are good quality. You can also find these in the “Other Helpful Sites” sidebar.
