So i can have fun, none of my loadouts work for me outside of my BR/Boltshot one
Here’s some of my loadouts if you’d like to try them.
DMR
Magnum
Plasma Grenade
Active Camouflage
AA Efficiency
Awareness
Play this class if you are primarily sniping or just long range. AA Efficiency allows your camo to recharge faster, and Awareness warns you when someone is too close.
DMR
Plasma Pistol
Plasma Grenade
Autosentry
Grenadier
Explosives
This is primarily for Big Team, use the plasma pistol to EMP annoying vehicles, and chuck plasma grenades at them. Grenadier lets you spawn with 3 grenades and Explosives increases the blast radius.
If you want, go ahead and add me. Always looking for people to play with!
Suppressor
Pistol
Pulse grenade/Frag grenade
Hologram
Mobility
Dexterity
Run around and cause mayhem. Its fun to me and I enjoy surprising people with this almost never used weapon.
Alternatively, you can just switch out the Suppressor with an Assault Rifle or a Storm Rifle.
Trust me, its much more fun the sitting with a DMR. 
K if your a fighting ninja type like me and assassinate anyone behind you this is my class always works for me but you have to know how to use the armor ability properly for ninjas
DMR
BOLTSHOT
THURSTER PACK
E EFINICY WHATEVER ITS CALLED
EXPLOSIVE TO GET DOUBLE KILLS IN A HALL OR UNDER YOU
DMR
Boltshot
Then it’s up to you, really.
I like frags, Thruster pack, dexterity, and resupply.
You can try Operator and Explosives along with with any weapons you want. (I suggest using explosives with Operator so you don’t die from grenades as easily while driving.)
I’m having fun with vehicles right now. Especially driving the Gauss Warthog. I love getting 20 to 30 wheelman medals in a game with 2 or 3 Gauss Warthogs. The only drawback is if you get a really really crappy gunner.
If I’m Blue team on Exile my record will usually look like 4 or 5 kills 4 or 5 deaths and 25 plus assists. My personal best was 33 wheelman assists on Exile and 26 wheelman assists on Longbow.
SO FUN!
This works for mostly objective game types but can work for slayer.
DMR
Boltshot
Frag Grenades
Promethean vision
Mobility
Explosives
Get to an area quickly, find your enemies and hit them hard with explosive range. Stand toe to toe against all ranges, and clear out small rooms with your grenades or boltshot. Especially good on King of the Hill or dominion.
DMR
AR/Pistol
Plasma
Jet pack
Firpower/Resupply
Stability/Ammo
