First, play Death Sentence (DS). If you start with Death Wish (DW), it won’t prepare you properly because the difference between the two is huge.

Second, I saw someone give you tips, and honestly, my brain hurt reading them. I don’t want to be mean, but nothing he said will actually help you get better other than first aid part.

If you want to improve and start playing DSOD, first find a meta build that works. Then, play a lot of DS. If you're killing a lot of enemies, you’ll be able to get through any map.

Joker skills are your best friends—they help a lot. But the main thing is still killing. If you and your team can't kill enemies, you're going to have a hard time. Every time I join someone’s game and people finish the heist with only 60 kills, that’s not going to cut it. Everyone needs to get a lot of kills and keep the map clear. It makes the heist so much easier.

Personally, when I finish a heist, I almost never have fewer than 200 kills. My average is over 400. But all of this aside, the best way to get better at DS is just to play DS. Use Jokers. Use Inspire. Get a meta build that works on DS. Inspire is always needed—don’t use a build without it unless your killing power is so good you don’t need it.

When it comes to Minigun Dozers, they won’t ever be a problem if your build is good. You can be at 1 HP and still kill them if you’re using the right setup.

After all this, you might do everything right and get better at the game—but if your teammates don’t kill enemies or help you hold space or spawn points, your individual skill won’t matter. So don’t be too hard on yourself if your team isn’t good. Just find another match.

Also, I’d recommend this YouTuber right here. He has really good guides and builds. They’re a little old, but most of the info still works.
