Here is a link to the Star Trek Online builds document. It is very informative and essential for end game ship builds.
This is a link for the MechWarrior Online PvP game and is one of the websites the clan uses to find various builds for a variety of mechs.
This is another website for mech builds that is also very good.
These are the two websites that some of us use for our character builds both are great but builds in this game are primarily based on play styles and opinions. Vulkk has a lot of popup ads just so you know otherwise a good site.
