Play to your team if you aren't comfortable carrying an engagement. A mediocre play that's supported is better than a good play that fails due to lack of support. Try to use weapons you're consistent with that fit the ranges if the map. Pulses and autos are comfy choices. Don't get ansty, all damage is good damage, but If you rush after a guy you almost killed just to get ganged up on, it's not worth it. Play confident, not overconfident. The map is a weapon. No other mode will teach you to play a map, and it's lanes like trials and the better you can play the map the easier time you'll have. I wish I could tell you a hundred more things but I'll leave it there before I might as well write a handbook.

My approach is what I lack in skill, I try to make up for with enthusiasm. It fails on a spectacular level, but that's all I've got. 😂

The best tip I can give is don't play too much like some people do. You'll either get burned out on it, or you'll start to just hate everyone else playing, or in the worst case scenario, you become a rager quitter and ruin matches for other people. Also, if you don't enjoy a type of crucible mode, don't play it. For some reason, some people in destiny don't understand that part.

maybe play some rumble first

Do you play on controller?
