here my tip

1) play 2vs2(get most kill with mech that equipped) or play catching point (get most point with the mech that equipped)

2) equip one weapon (Fusion Cannon 6) and another one with strong weapon like dics launcher or javelin

(since Fusion Cannon 6 has 2 weapon, you can equip with different)

(if 2 mech with Fusion Cannon 6 MVP, you has 2 point in one match)

3) find team, ally, or friend that can help you

I would recommend suggestion #2 from Pahlawan Suzaku. Equip Fusion 6 in one arm and an actually good weapon in the other. Alternatively, you can equip it on a fast mech (surge, killshot, slingshot) and go around getting captures of control points. Usually 2-3 captures + 1 kill or assist is enough for MvP.

Still, that task is painful with such a weak weapon!

Best bet is to play cpc and captures points with it equipped on a fast mech; dont need kills to get an mvp spot. Like mentioned earlier, play with a team. Make it known you are trying to get mvp with the weapon and most players are helpful in that regard to help you get the objective.

my opinion is to play 2v2 with bots which is normally get in every match or battle and get a disc launcher in one arm and in other arm a fusion cannon with guardian mech and another do it with a panther also combination of disc launcher and fusion cannon or u can use the combination of missile rack 6 or 8 and a fusion cannon with killshot with 4 or upper rank.
