Similar to the SHD builds around this one is ment for medium and long range fire support. Use your ACs for suppressing opponents. Don't hesitate to pull the trigger - ammo is plenty. The MLas are for short range defense and are completing the loadout. For this specific role the speed required only has to be as high as the average heavy mech's, as you usually want to join their pack. A STD 225 would be possible as well, though.
