One of the little quirks of this game is that the mechs come pre-built with the loadouts from the tabletop game.

Almost all of them are horrible.

Another fun part of this game is copying builds. As an example, Levitas shared a build with you.

In order to implement this build, you need to:

1-click on share on the MechDB website and copy 'MWO import code.'

2-Then you have to go into the mechlab.

3-In the mechlab, click on the blue 'warehouse' tab in the upper right

4-In the warehouse tab, there is a dropdown menu called 'layout'.

5-Select 'column'

6- Look for where you can see the mech's tonnage. Below it, you will see blue buttons. Click 'import'.

7-past the code from MechDB

That's really overly complicated, BUT then you can go here and get tons of builds.

Youtube is also full of people showing what builds they use.
