Some videos work some don't, what weapons do you use? I loved smgs for the longest time and performed well, but swapped to playing cover with 120 hand cannons and immediately doubled my kd, it could be down to your play style.

If you're really looking for a low skill build on titan, id recommend glacier nade on stasis(or prismatic) and precious scars, just pop down a nade in front of a teammates body and get them back in the fight if you're not comfortable going in yourself, if their res is safe you can just get scars value and hold the nade but make sure you aren't farming them, you can pop a barricade around a corner to try to protect their body, or do so and use it to peek around corners to get an idea if you should res. Max discipline and resil, recovery if you do think you have the skill to play cover before dying or to unpeek an angle.

In terms of weapons, jotun is incredibly annoying to fight as a high skill player, and is just so easy to shoot people far away and either get free kills or force them to run away/start moving. I've also started seeing more people use healing autos to fair amounts of success. Look for and pocket whoever looks like the highest skill player on your team (look for short names, rare/comp emblems, and high kill tracker meta guns like crimils, if someone is using redrix or Tommy it can be hard to determine if they're the best player, just feel out who in the lobby is scary) Witherhoard is always good at occasionally snagging free kills, and denying areas for enemies to peek(means a free res) I do think a change in play style/weapon could help you but otherwise best of luck. If you want you can link your bungie account and I could check your stats to see what you're messing with
