I'm liking the hold last word, red death and Monte Carlo for primary weapon .

If you have a Titan- shoulder charge [i]a lot[/i]. Its a One Hit Kill, but easily countered by shotguns and supers. Sunbreaker is hard to take down, plus its a free Golden Gun mixed with Nova Bomb. It's weird. Use Fist of Havoc when there are minimum 2 enemies for more points, or use it 1v1 if you are dangerously low (personal choice) If you use Hunter- take the Precision throwing knife perk on Gunslinger, hit an enemy once or twice then throw the knife. Boom, instakill. Golden gun is a free 3 kills minimum without Keyhole perk. Blade Dancer is meh right now. If you use Warlock- Nova bomb seems to be the best way to go in regular crucible. I can't see another plus side to Warlocks in crucible besides Nova bomb, blink, and that Void Grenade that follows you across the whole damn map. Go for Heavy ammo whenever you're near one, and [i]always[/i] expect an enemy to go for that same one. Solution?: Watch your minimap and see if someone is near that ammo spawn if you go for it. Sprint when you move, slide when someone's shooting at you, [i]always[/i] melee if you are in range, guns aren't that reliable in close quarters (besides Shotguns, and some Hand Cannons). (In your situation) Pulse Rifles are the best primaries. Shotgunsare the best secondaries. Rocket Launchers are the best Heavies. Save scout rifles and snipers for those HUGE maps with lots of open areas and Rusted Lands. If you have Vestian Dynasty, use it. Takes no skill to point and literally [i]spam[/i] fire that thing. I brought my Titan K/D from 0.7 to 1.2 now using those methods. Rest is just common sense. Be unpredictable, eyes on radar, choose appropriate weapons according to each map, and if you think you are in danger but want to make a play, stay back and wait for your health to regen, or yolo it and see what happens. P.S. while you're flying to the planet where the map is, press start -> roster-> look right -> inspect other players -> counter them -> profit.

Don't die. Play safe, get kills later. If you have to become an assist machine, so be it. Also just play and get better at aiming. Practice, practice, practice. Try lowering and raising your sensitivity to find the right one for you. Weapons won't help you improve. Practice the fundamentals imstead.

I'm no help just went from 49% down to 10% for my chaperone quest needless to say I was salty

No gun is going to help if you can't aim it, excepting a shotgun of course. Please don't fall to the dark side. Practice your gun skill at all times, in Crucible and elsewhere. You'll get there eventually.

Sidearms

Pulse rifles and shotguns are a good combo
